Cross-correlated spin relaxation effects in methyl 1H CPMG-based relaxation dispersion experiments: complications and a simple solution.

Abstract

Artifacts associated with the measurement of methyl (1)H single quantum CPMG-based relaxation dispersion profiles are described. These artifacts arise due to the combination of cross-correlated spin relaxation effects involving intra-methyl (1)H-(1)H dipolar interactions and imperfections in (1)H refocusing pulses that are applied during CPMG intervals that… (More)
