Offset dependence of homonuclear hartmann-hahn transfer based on residual dipolar couplings in solution state NMR

The offset dependence of homonuclear Hartmann-Hahn transfer is markedly different if a given multiple-pulse sequence is applied to dipolar coupled spins or to isotropically coupled spins. The different offset dependence of the transfer efficiency is studied by numerical simulations of a multiple-pulse sequence and by the analytical treatment of a simple model experiment.
