Abstract
A theoretical analysis is presented for Liquid-state T-1p relaxation i n a coupled two-spin system I = 1/2, S=1 in the presence of two radio- frequency fields applied to each of the spins individually. It is demo nstrated that the relaxation rate constant T-1p(-1) of the spin I due to scalar relaxation sharply increases when the two radio-frequency fi elds are matched according to the Hartmann-Hahn condition. Relaxation measurements on the amino-protons of 3-nitroaniline show good agreemen t with theory. (C) 1998 American Institute of Physics.
