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.
