摘要：

A method for the calculation of the Hartmann-Hahn matching curve in 1H13C cross polarization and magic-angle spinning NMR experiments is proposed. The theoretical results are compared to experimental data. The basis of the theoretical approach is a two-step autocorrelation function calculation using Mori's integrodifferential equation as a starting point for the introduction of suitable approximations (Anderson-Weiss-type approximation and short correlation limit) to find a description of the spin dynamics of the coupled 1H and 13C spin system under magic-angle-spinning conditions. © 1991.
