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
The 1:1 complex between the zwitterionic piperidinium-3-carboxylate (P3C) and salicylic acid (SAL), P3CΓSAL, has been characterized by single crystal X-ray analysis, FTIR and NMR spectroscopy, and by DFT calculations. The crystals are orthorhombic, space group Pbca, with a = 11.6477( 7), b = 9.1754(
1 H and 15 N NMR spectra of 10 complexes exhibiting strong OHN hydrogen bonds formed by 15 N-labeled collidine and different proton donors, partially deuterated in mobile proton sites, have been observed by low-temperature NMR spectroscopy using a low-freezing CDF 3 /CDF 2 Cl mixture as polar aproti
