A detailed formulation is presented for the analysis of slow motional ESR in terms of the
reorientation of the probe molecule within a dynamic solvent cage. This formulation is …

It is shown that the commonly used models for analyzing ESR spectra from nitroxide spin-
labeled proteins or DNA systems are special cases of the more general slowly relaxing local …

The nitroxide spin label 1-oxyl-2, 2, 5, 5-tetramethylpyrroline-3-methyl-methanethiosulfonate
(MTSSL), commonly used in site-directed spin labeling of proteins, is studied with molecular …

The two-body Slowly Relaxing Local Structure (SRLS) model was applied to 15N NMR spin
relaxation in proteins and compared with the commonly used original and extended model …

NMR relaxation experiments have provided a wealth of information about molecular motions
in macromolecules and ordered fluids. Even though a rigorous theory of spin relaxation is …

Protein dynamics by NMR has been reviewed extensively in recent years [1–10]. These
surveys show decisively that information on structure should be complemented by …
