Vibration Spectra and Molecular Structure VI. Infra-Red Absorption Spectrum of Heavy Formic Acid

Abstract

The infra-red absorption spectra between 1 and 15.5μ of the monomer and dimer of HCOOD have been found with a rocksalt prism spectrometer. The position of the vibration characteristic of the ``deuterium bond'' in HCOOD has been determined and permits an approximate calculation of the shorter OD distance in the dimer ring. As in CH3COOD the distance is found to be 1.07A.
