TL;DR: In this paper, the NQR spectrum of 35 Cl nuclei for complexes of pentachlorophenol with nitrogen bases has been studied as a function of pressure and temperature, and it is shown that the value of the pressure coefficient of the nQR frequency is related to the degree of proton transfer.
Abstract: The NQR spectrum of 35 Cl nuclei for complexes of pentachlorophenol with nitrogen bases has been studied as a function of pressure and temperature. It is shown that the value of the pressure coefficient of the NQR frequency is related to the degree of proton transfer. A distinct anomaly of the pressure coefficient of the NQR frequency in the vicinity of 50% proton transfer hydrogen bonds has been observed. The phenomena have been interpreted on the basis of the Matsushita and Matsubara model and by assuming the pressure dependence of proton transfer equilibrium. The influence of the crystal effect and torsional vibrations on the temperature-pressure characteristics of the NQR spectrum is discussed.
