35Cl NQR frequencies and spin-lattice relaxation times T1Q were measured in p-ClC6H4CO2H(PCB A) and p-ClC6H4CO2D(PCBA-d1) at 77-333 K. T1Q in PCB A gave a shallow minimum of 8.0 ms at ca. 110 K, which could be explained by a double proton transfer mechanism in the carboxylic acid dimer referring to 1H NMR data giving a T1H minimum at almost the same temperature. PCBA-d1, showed temperature dependent NQR frequencies quite analogous to those in PCBA, whereas their T1Q behaviour was quite different in its minimum value and its temperature as well as temperature gradient. These results were explained by suppressed deuteron tunnelling and the Ubbelohde effect.
