Abstract
The temperature dependence of the Cl-35 NQR line and its relaxation has bee n measured from 77 K to room temperature. The known displacive phase transi tion near 162 K is reflected in the change of the slope of the temperature dependence of the quadrupole line, but not so in the chlorine or proton rel axation. The results are discussed in view of the proposed structural chang es and thermal vibrations.
