✦ Synopsis

Incoherent neutron scattering experiments have been performed on the disordered hydrogen-bonded dimers of terephthalic acid. An abnormally high Debye-Wailer factor is found in contradiction to a simple t\o-site jump model. The inelastic incoherent neutron spectrum is analyzed by using different isoropicdly substituted molecules. The resulrs are cornpared with the Arrhenius parameters of the exchange process obtained by solid-state NMR experiments.

Proton (deuteron) transfer ofhydrogen bonds in benzoic, glutark and pformylbenzoic acids was studied by proton (deuteron) T, measurements. Deuteration of carboxylic protons was found to increase the barriers to classical proton jumping as well as quantum-mechanical tunneling. The former barriers inc
