NMR-Verhalten eines Zwei-Spin-Systems im Festkörper ohne longitudinale Relaxation

N.M.R. Theory of a Two-Spin System in a Solid without Spin Lattice Relaxation Starting from the exact solution of the equation of motion for a two-spin system in the case of continuous rf irradiation the mean values of magnetization and the dynamic behaviour were analysed and compared with n.m.r. theories of solids. In most cases we obtained a good agreement. Basic differences between two-spin systems and solids were discussed. We derived general conditions for the adjustment of pulse cycles and investigated the behaviour in the case of misadjustment.
