Abstract

An analysis of the vibrational spectra of the bent triatomic molecules HCO and DCO has been performed using algebraic methods. A model based on coupled U(2) algebras has been proposed for the description of the vibrational spectrum of HCO. The vibron model, based on the U(4) Lie algebras, has then been applied for the calculation of the vibrational spectra of the HCO and DCO molecules. The calculated spectra have been compared with the available experimental data as well as with ab initio calculations. The results show that the vibron model provides a description of the experimental data of comparable accuracy to that provided by ab initio calculations. © 1993 Academic Press, Inc.
