The redirect
... from 2D-NMR is not very accurate as a 2D NMR experiment is not necessarily a Correlation experiment. Ideally we'd have an introductory page about general 2D principles and then pages on the individual techniques... ACH (talk) 17:11, 29 January 2009 (UTC)

Interpreting the COSY image data?
I'd like a little more information about the COSY-generated image. Looking at this, it appears that spots on the image can represent geometric relationships between neighboring atoms, but the details aren't too clear. What is "PPM" in this usage? It appears to be a frequency rather than a concentration (parts per million). If this kind of information is too elementary to have a place in the article, there might at least be pointers to *.edu websites where this stuff can be found. -- WillWare (talk) 13:37, 7 May 2011 (UTC)

In terms of the ppm notation, those with a background understanding of NMR will know that you usually deal with chemical shift in ppm, and all spectra are recorded as such. I also doubt that anyone will be looking specifically for COSY experiments without having this kind of background. WCSpaz (talk) 12:16, 3 June 2011 (UTC)

NOESY section
I think that NOESY shouldn't be considered as a sub-section of COSY, as they are completely different types of experiment. They should either both come under a heading of 2D NMR experiments, or NOESY should be discussed under its own page. WCSpaz (talk) 12:19, 3 June 2011 (UTC)


 * I just moved this article from Correlation spectroscopy to Two-dimensional nuclear magnetic resonance spectroscopy to better reflect the content. Seperate articles on COSY and NOESY etc. can be split off once there is more detailed content.  Antony–22 (talk⁄contribs) 02:36, 6 June 2011 (UTC)


 * Actually, Schraml splits NMR methods into "resolved" and "correlated" groups, and counts NOESY as a correlated method. It's just that the correlations are through-space instead of through-bond.  Antony–22 (talk⁄contribs) 21:49, 1 July 2011 (UTC)

Heteronuclear single quantum coherence
HSQC (Heteronuclear single quantum coherence) is also a common 2D NMR technique, and should be included in the article — Preceding unsigned comment added by 62.198.80.252 (talk) 16:40, 8 June 2011 (UTC)


 * Indeed! Could you write a paragraph or two about it? Wikipedia thrives from reader contributions. DMacks (talk) 16:54, 8 June 2011 (UTC)

DOSY NMR
Would the article benefit from a section on DOSY NMR? It's somewhat different than the other techniques, but in the end it's a 2D-technique, too.92.206.140.148 (talk)


 * Absolutely! Contributions are always welcome; please feel free to be bold and add a section, and if you have any questions I'll be happy to try to answer them.  Antony–22 (talk⁄contribs) 17:18, 5 February 2012 (UTC)
