Abstract
A quantum-statistical method is used to study the structure of the NMR spectrum under adiabatic orientation-modulated (OM) magnetically anisotropic Hamiltonian of a nuclear system by rotational oscillation of a crystal about a fixed axis. A general expression is obtained for an NMR absorption signal, in phase with the OM, which reflects the main anomalies of such a spectrum. The results are used to interpret the OM NMR spectrum in spin systems with weak axisymmetric nuclear quadrupole interactions.
