A method is proposed for direct mapping of spectral density functions of the rotational motions of H-X bond vectors, such as 1H---15N, by measuring a set of NMR relaxation parameters. The well known and frequently measured relaxation parameters T1 and T2 probe the spectral density function J...

Spectral density mapping at multiple NMR field strengths is probably the best method to describe the dynamics behavior of a protein in solution through the analysis of 15N heteronuclear relaxation parameters. Nevertheless, such analysis is scarcely reported in the literature, probably because this ...
