摘要: The 35Cl nuclear quadrupole resonance (NQR) frequencies (V Q) in caesium and sodium chlorates were measured as a function of temperature, from 77 to 300 K at different pressures up 5.1 kbar, the data analysed estimate volume dependence electric field gradient (EFG), torsional frequency also contributions NQR static dynamic effects. variation spin-lattice relaxation time with pressure temperatures was studied case chlorate room temperature chlorate. (T1) suggests that is mainly due motions. Copyright © 2008 John Wiley & Sons, Ltd.
