Abstract
Normal coordinate analyses have been made both for dimeric formic acid and acetic acid, including their deutero analogs. The Urey—Bradley force constants of the dimers have been compared with those of the corresponding monomers to study the effect of hydrogen bonding on individual bonds. Theoretical band assignments have been made for all the in‐plane vibrations based on the potential energy distribution. The results reveal the nature of vibrational couplings which have hitherto been assumed only on an empirical basis.Keywords
