Microwave spectra of CuOD and AgOD: Molecular structure and harmonic force field of CuOH and AgOH

Abstract

Pure rotational spectra are reported for the deuterated species of copper and silver hydroxide, 63 CuOD , 107 AgOD , and 109 AgOD . Together with the CuOH and AgOH data previously reported, a number of harmonic force constants were determined. These constants are interpreted in terms of the balance between competing ionic and covalent interactions. The harmonic force field allowed the r z structures to be determined. Both molecules are strongly bent indicating considerable covalent character.
