Abstract
The Cl-35 and Br-79, Br-81 NQR spectra of(C5H5)2M Hal2 (M = Ti, Mo, W, Zr, Hf; Hal = Cl, Br) are similar. They are quadruplets with splittin gs ranging from 2 to 7%. The averaged frequencies of chlorine and brom ine are related by a linear dependence. The temperature dependence of Br-81 in Cp2HfBr2 (in the range of 77 is-approximately-equal-to 224 K) is of conventional character with frequencies slowly changing wit tem perature; phase transitions have not been observed.
