Аннотация: The direct spin-lattice relaxation due to local thermal fluctuations of the amplitude of the atomic-displacement wave -in the incommensurate phase of a crystal can strongly influence the lineshape of the resonant spectrum, reducing the intensity of the outermost temperature-dependent peaks in the frequency distribution, while having essentially no effect on the temperature-independent features of this distribution. This effect is apparently the reason for the anomalous behavior of the NQR spectrum of I-127 in Cs2ZnI4 in a certain temperature interval near the transition from the ''normal'' phase to the incommensurate phase.
