Abstract
A zero-quantum/double-quantum HNCO(H) constant time experiment is presented for the quantitative evaluation of dipole-CSA cross-correlated relaxation involving the 1HN, 15N, and 13C' nuclei of the peptide plane. A simple procedure that allows the extraction of cross-correlated relaxation rate constants from intensity ratios of well-resolved doublet components along omega1 is described. The experiment is demonstrated on fully 13C, 15N-labeled ubiquitin.
