Fig. 1. Theoretical values of the spin-lattice relaxation rate (a l/T, —), off-resonance nonselective nuclear Overhauser effect (NOE b), rotating (fame spin - lattice relaxation rate (a l/ n )t linewidth (a,—), and off-resonance intensity ratio (R c) for P at 40.5 MHz. The random, isotropic motion model vtras utilized, as described in the text. The computed curves assume relaxation only from three protons that are 2.6 A way from the phosphorus. The and R curves were calculated assuming an off-resonance field of 0.47 G applied 8 kHz off-resonance. From Bolton and James (1980a). Copyright 1980 American Chemical Society.
