Formatting

Hello,

Does the formatting look fine? As you can see by clicking the history tab, and the compare button, one needs to put titles between "==" to have them appear in the Table of contents. If you wish to make subsections, just use "===" and even "====". However, Citizendium disapproves excessively "modular" articles (with many subsections), and prefers lively narratives, but I can see that you are certainly not going in that direction (the excessively modular approach)! If I can help in any way (I'm just an author, however), please let me know by clicking my user name and then the "discussion" tab, where you can "edit" at the bottom of the page.

I removed your signature from the article, because those who wish to know who has been working on a given page normally click on the "history" button. I will now create redirect pages, which will enable users to access this page using the different abbreviations and alternate names you provide.

Some formatting pointers

Dear dr. Talluri, welcome again. I hope that you will contribute more articles of the same quality. I understand that you don't have any wiki experience yet. Therefore I mention a few things:

The wiki software knows LaTeX enclosed between <math> ... </math> An indented new paragraph is started by a colon (:),

like this. Hence indented math uses   :<math> ... </math>

As in printed text (in journals etc.) emphasis is done by italics, not by capitals (and also not by underlining). Wikilinks are done as [[NMR spectroscopy]] and give NMR spectroscopy.

If you don't want to be bothered by these finicky details, don't worry, others (including myself) will fix it. It is more important that you share your knowledge and expertise with us than that the format is perfect. --Paul Wormer 03:32, 13 January 2008 (CST)

I didn't nominate for approval, but it says i did

I have no idea why the article says I nonimated it for approval. I have not even read it through yet. Any help appreciated removing the approval. David E. Volk 16:38, 16 January 2008 (CST)

Editors, this article is set for approval tomorrow. As it is using the group editor approval method, it requires three editors to be on the template. David appears to be suggesting that he has not recommended it for approval(it's a year old?). Unless I hear otherwise, the comment above means I cannot perform the approval. D. Matt Innis 02:06, 17 January 2009 (UTC)

Way to go.

I see that the article is developing nicely, keep up the good work.--Paul Wormer 11:03, 19 January 2008 (CST)

The lede

This is turning into a really great article. We do need to improve the lede however to interest the casual reader. I have been refraining from working on the article so I could approve it later, but I forgot and wrote a liitle today, now we will need three editors for approval when ready. If we can spiff the rough edges, we can nominate for article of the week David E. Volk 14:09, 15 October 2008 (UTC)

Approval potential

Hello editors, I see three editors on the ToApprove template above, but am not convinced that all three are ready to approve the version chosen. Please leave a message here so that when I return tomorrow, I can be sure that all three are endorsing the version number that you choose (please make that clear as well by updating the version number in the template). Thanks, D. Matt Innis 02:12, 17 January 2009 (UTC)/constable

My name was incorrectly added to the Metadata template, without my knowledge, as an Approval nominator. Although I am a Chemistry Editor and a Physics Editor, I don't know enough about NMR to review or to approve this article. My name should be removed. Milton Beychok 02:56, 17 January 2009 (UTC)

I will start reading it tomorrow (January 18) and need, say, a week. I can approve it by myself, but I believe that David Volk and Daniel Mietchen are much better qualified. When they have time that would be nice. In any case I will put my name down and January 25 as approval date. If Daniel and David need more time they can move the date forward (or is it backward? I never know, I mean later). --Paul Wormer 16:22, 17 January 2009 (UTC)

minor changes please

This is looking great. First, minor edits needed:

1. Section 2.1 uncapitalize tetramethylsilane since it is mid-sentence
2. Section 2.2 repeat of "results results" should be edited
3. For the FID diagram, fix the figure legend
4. In the Biomedical section, remove cap letter on Sequential; it is mid-sentence

As for the layout: I would like to see a 1D and 2D spectrum near the top to give the new reader an idea of what they look like right at the start. I would also like to see an example of metabonomics (metabolomics) NMR taken from the literature, but that can wait for the next version.

Since I have refrained from working on this article (I think that is true), I can approve it single-handedly once the minor corrections are made by the principle author or Dr. Wormer. I have many images which I could upload and someone else can insert into the article. David E. Volk 16:36, 17 January 2009 (UTC)

my minor edits

It appears I accidently made very minor edits previously. Perhaps the constables can forgive such minor edits and still let me approve it. David E. Volk 16:39, 17 January 2009 (UTC)

Hi David, you are allowed to make copy edits to the text and still use the single editor approval, so you can make those that you have listed above - as long as you don't make any content changes. You can suggest content changes here on the talk page and others can make them for you. The edits that I saw from previously no longer exist as they have been integrated into the new version, so I don't see any problem with continuing with a single editor approval at this point, if that is what you are willing to do.

A brief review

• I am glad this article has been developing nicely recently, as I had planned to work a bit more systematically on Nuclear magnetic resonance, MRI, Neuroimaging, DTI, fMRI in the near future. Since NMR spectroscopy is probably going to be the first approved MR article and thus basically sets the stage on how MR and related concepts are going to be presented here at CZ, I would like to have a bit more time to develop a coherent structure for this set of articles (preferably via the respective "realted articles" subpages). As a first step in this direction, I just moved the "NMR principle" section to Nuclear magnetic resonance where it can be developed independently, without interfering with this one's approval (might be good to move the Catalog there, too).

• I did not have time to go through the NMR spectroscopy cluster in detail but I think that at least the following points should be addressed before approving it:

1. I miss mention of some relevant concepts (e.g. line splitting, magnetization transfer, hyperpolarization, remote detection, localized spectroscopy and chemical shift imaging) as well as mention of the respective contributions of prominent pioneers, at least the relevant Nobel prize winners (Stern, Rabi, Bloch, Purcell, Ernst, Wüthrich, and perhaps Mansfield/ Lauterbur, too) - some brief phrases and/or redlinks may do for the moment (I will help with that)
2. Intrawiki linking from here should be made more coherent (I will help with that)
3. The content on the subpages should be properly formatted (I will do this for the bibliography, as I am working on ref formatting anyway) and annotated

• I have thus extended the deadline to Feb 2 and envision Sekhar, David and me as approving this cluster by then.

--Daniel Mietchen 01:24, 18 January 2009 (UTC)

• Re: 1 : please see the nmr spectroscopy advanced tab for a brief mention of 'non-conventional' NMR spectroscopy techniques such remote detection. As this is an INTRODUCTORY article all concepts cannot be discussed in detail. I believe a stub should be added for each of the topics that you have mentioned. But that can be done later.
• The work of the pioneers is adequately referenced -- please examine the references section where references start with work of Rabi, Bloembergen, Pound, Purcell, etc. I did not mention Stern because Rabi's molecular beam experiments were the first demonstration of NUCLEAR magnetic resonance (gotta start somewhere:-). Work of Ernst (in FTNMR section) and Wuthrich (biomolecular NMR section) is also referenced. See the Applications of Magnetic resonance in Pharmacology, Physiology and Medicine section for references to pioneering work of Lauterber,Mansfield,Ernst,Lee on MRI. I have not mentioned the name of the pioneers in the text, but the work is adequately referenced if you examine the references that site the work. Assigning credit to pioneers has to be done with great care and can be controversial, e.g., though most people in the medical MRI field believe that Lauterber was the pioneer for MRI, it is clear that the unrelated work of Lee (Nobel96) and coworkers (published earlier than Lauterber) not only introduced the concept of determination of spatial positions using field gradients but also successfully implemented it, though the focus of their work was on an unrelated topic (phase transitions in superfluid He). (As I do not have access to a decent library, I preferred not to become responsible for assigning credit, as I am mostly writing from memory/other sources from the internet/personal textbooks).
• The concept of sensitivity enhancement by magnetization transfer has been introduced briefly in the Nuclear Overhauser effect stub (see also the advanced section). However, the more common methods of magnetization transfer using pulsed RF fields would be difficult to introduce as the theory of RF spectroscopy is not adequately developed at this level. Specialized techniques such as chemical shift imaging require a stub of their own or a complete article. Also, I believe, and I think that D.E.Volk will agree with me that biomolecular NMR spectroscopy requires one or more complete and independent articles to which this will be only an introduction. He has made a list of NMR experiments and EACH of these requires a minimum of a page.
• the present article can be regarded as a compromise between introducing and explaining the essential concepts while keeping the length manageable and the level accessible to a newbie. However, the focus of this article is on the concepts of importance to solution NMR spectroscopy (primarily because this is what I am most familiar with) - a separate and complete article on solid state NMR spectroscopy and/or MRI would be complimentary and could introduce additional important concepts.

Sekhar Talluri 07:08, 18 January 2009 (UTC)

In my opinion it would be best to start four articles: one introducing solution NMR spectroscopy (this one), one introducing solid state NMR, one introducing MRI and one introducing instrumentation and 'non-conventional' NMR techniques such as zero-field NMR, noise for excitation, remote detection, field cycling, ODNMR, hyperpolarization, SQUID based detection, Dynamic Nuclear Polarization, etc. And then when all are approved have a 'grand synthesis' page for 'introduction to magnetic resonance' either linking these articles or merging them together into a single coherent article. Such a bottom up approach is likely to result in many more articles that are quickly approved and made available in pieces. The end result would be the same as a top down approach which would require much more time than Feb.2, if I am required to make any more substantial contributions (It took me 8.5 years to get my Ph.D!). However, this is only an opinion, I have no objection if you try it the other way round. Sekhar Talluri 07:46, 18 January 2009 (UTC)

I mentioned earlier on this page, I work on this only during holidays when my internet connection at home is working (it works sometimes and sometimes does not!). Best wishes. Sekhar Talluri 09:33, 18 January 2009 (UTC)

Approval comment

Good to see you guys working this so well. Just to be clear, you can approve an article without its cluster if you like, but certainly feel free to get it all up to par. Also, as Sekhar is an author, we would either need another editor on board, or David can give his ideas here on the talk page and Daniel or Sekhar can collaborate with him here to get them into the article. That way he will be able to use the single editor approval method and we will know that all of you agreed with his content issues as you put them in. Others can help as well with content and copy edits. Make sure to update the version number once you are all agreed and then I'll return on February 2 to lock it down for you. D.
