Does anyone know of literature pointing to NMR experiments that can select for say -CH3 groups attached to -CH2? |
If you are asking about amino acid side chain selective experiments ( since I noticed protein and side chain tags on your post) then you should look at the MUSIC family of pulse sequence by Mario Schubert. |
I know a commercial platform that provides custom protein analysis services NMR.Creative Biostructure MagHelix™ Nuclear Magnetic Resonance, hope helpful. |
