Normal Coordinate Analyses of Hydrogen-Bonded Compounds. I. Monomeric Formic Acid and Acetic Acid

Abstract
In order to obtain the Urey—Bradley force constants, normal coordinate analyses have been carried out for monomeric formic acid and acetic acid including their deutero analogs. Previous empirical band assignments have been confirmed or corrected on the basis of the calculation of the potential‐energy distribution in each normal vibration.
