Should I decouple deuterium on 2H/15N labeled sample for R1, R2 and hetnoe?

0	If I'm running relaxation experiments (15N) for R1, R2, and hetnoe on a double labeled (2H/15N) sample, do I need to do any deuterium decoupling added to the program? deuterium decoupling asked Aug 18 '10 at 10:02 anita 31

If the object is to measure 15N relaxation rates (R1, R2 and hetnoe), and if the experiment is being carried out in 90%H2O/10%D2O, then it would not be necessary to do deuterium decoupling for a doubly labeled (2H/15N) sample.

However, if the experiment is carried out with different compositions of solvent (H2O/D2O ratios) and deuterium decoupling is applied then additional information would be obtained for elucidating the contribution of an additional mechanism of relaxation for 15N amide nuclei having exchangeable protons/deuterons.
