Title: 2D NMR
Post by: che-mistry on November 12, 2012, 04:43:27 PM

Hello,

How to solve NOESY spectrum and How to assign the coupling constants (for example dddd).

looking forward to more info ....Thanks

Your question is too broad for an internet forum. Get a book about organic spectroscopy from your library, some general organic texts even have a chapter on this - it is too much material to be reproduced here. Have a read and then come back with more specific questions.

Examples of books:

http://www.amazon.co.uk/Understanding-NMR-Spectroscopy-James-Keeler/dp/0470017872

You can probably also find decent NMR tutorials on the web with a bit of googling. Possibly useful search terms might be "NMR splitting patterns", "2D NMR correlation experiments", "nuclear Overhauser effect" etc., but I would recommend getting a textbook that will start you off with the basics (like splitting patterns) and logically guide you to more complicated areas (like 2D NMR and NOE).
