摘要：

The Cl35 nuclear-quadrupole-resonance (NQR) spin-lattice relaxation rate in incommensurate bis(4-chlorophenyl)sulfone (BCPS) is determined by Raman processes below 60 K and by direct one-phonon processes above 60 K. The variation of the Cl35 spin-lattice relaxation rate over the incommensurate NQR frequency distribution in BCPS has been also measured at various temperatures. The results are explained in terms of phason and amplitudon contributions to the effective spin-lattice relaxation rate. In contrast to Rb2ZnCl4-type crystals the changes in the Cl electric-field-gradient tensor produced by modulation wave fluctuations contain both first- and second-derivative terms. © 1995 The American Physical Society.
