Infra-red spectra and dipole moments of hydrogen-bonded complexes. Part 5.—Proton transfer in carboxylic acid–pyridine complexes
Abstract
Dipole moments and hydrogen bond polarities of 16 complexes of carboxylic acids with pyridine and 8 of chloroacetic acid and trifluoroacetic acid with pyridine and its derivatives in benzene solutions have been determined. Proton-transfer in these systems is discussed and good agreement with spectroscopic data of other authors is obtained.
