The present paper reports the achievement of the rotating-frame analog of spin-locking and its application to the precise measurements of the spin-lattice relaxation time T(1DR) in the doubly rotating frame. After the magnetization is aligned along the resonant RF field H(1), a pulse sequence of a l
15N off-resonance rotating frame relaxation can be applied to the study of internal dynamics in proteins in the millisecond to microsecond regime. We show that the performance of existing methods can be improved by application of simultaneous amplitude and phase-modulated adiabatic RF pulses to alig
With the NMR lineshape-relaxation correlation technique the relaxation times and the relative magnitudes of the proton spin groups characterized by these respective relaxation times are obtained. In most tissues the spin-lattice relaxation in the rotating frame is nonexponential. The magnetization e
## Abstract The application of rotating frame spinβlattice relaxtion to the determination of the intramolecular motions in peptides is discussed, and results are presented on the application of ^13^C __T__~1__p__~ to peptide microdynamics in solution. The effective molecular rotational reorientatio
