The vibrational spectra of several isotopic species of BH3CO in neon matrices at 10 °K have been observed. A number of combination bands have also been observed, leading to an assignment of most of the fundamental harmonic frequencies of these isotopic species. A least squares normal coordinate treatment, without constraints, has estimated a set of potential constants. We can conclude that the CO bond in BH3CO is slightly stronger than that of free CO. The interaction coordinates suggest that unimolecular dissociation of the B–C bond proceeds initially toward BH−3+CO+ but reverts to BH3+CO before dissociation.
