[Question from NMRWiki Q&A forum] Should I decouple deuterium on 2H/15N labeled sample for R1, R2 and hetnoe?
Should I decouple deuterium on 2H/15N labeled sample for R1, R2 and hetnoe?
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?

Structure determination of proteins in 2H2O solution aided by a deuterium-decoupled 3
Abstract We developed an NMR pulse sequence, 3D HCA(N)CO, to correlate the chemical shifts of protein backbone 1Hα and 13Cα to those of 13C� in the preceding residue. By applying 2H decoupling, the experiment was accomplished with high sensitivity comparable to that of HCA(CO)N. When combined with HCACO, HCAN and HCA(CO)N, the HCA(N)CO sequence allows the sequential assignment using backbone 13C� and amide 15N chemical shifts without resort to backbone amide protons. This assignment strategy was demonstrated for 13C/15N-labeled GB1 dissolved in 2H2O. The quality of the GB1 structure...
