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? |
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. |
