摘要

By ~(35)Cl NQR the temperature dependences of the resonance frequencies and spin-lattice relaxation times for the ~(35)Cl nuclei have been studied in solid CCl_3COHal (Hal = F, Cl, Br, I). A linear correlation between the average ~(35)Cl NQR frequencies of the CCl_3 groups and the electronegativ-ities of the halogen atoms in the COHal groups has been discovered. The temperature-dependent NQR data reveal thermoactivated reorientations of the CCl_3COHal molecules as a whole in the crystal lattice. The activation energies of this motion are found to lie in the range 31-37 kJ mol~(-1).
