 Pressure Dependence of the Chlorine NQR in Three Solid Chloro Anisoles    Abstract
 The 35C1 Nuclear Quadrupole Resonance (NQR) frequency (V q) and spin lattice relaxation time (T{) in the three anisoles 2,3,4trichloroanisole, 2,3,6trichloroanisole and 3,5dichloroanisole have been measured as a function of pressure upto 5.1 kbar at 300 K, and the data have been analysed to estimate the temperature coefficients of the NQR frequency at constant volume. All the three com pounds show a non linear variation of the NQR frequency with pressure, the rate of which is positive and decreases with increasing pressure. In case of 3,5dichloroanisole the value becomes negative in the higher range of pressure studied. The spin lattice relaxation time T{ in all the three compounds shows a weak dependence on pressure, indicating that the relaxation is mainly due to the torsional motions.
