^<35>Cl nuclear quadrupole resonance study was carried out on CsH(CHCl_2COO)_2. The Zeeman effect experiment shoxed that this crystal belongs to a triclinic sustem with two crystallograohically nonequivaqent dichloroacetare anions. From the measurement of the temperature dependence of the resonance frequencies and the soin-lattice relaxation times of all the four resonance lines it was found that the CHCl_2 groups in one of the two carboxylate anions undergo internal rotation about C-C bonds below room temperature with the activation energy of 3.97 kcal/mol. Dielectric behavior was consistenr with the motion. The nuclear quadrupole resonance frequencies of 17 other chloroacetates are also reported.
