✦ Synopsis

An analysis of the vibrational spectra of the bent triatomic molecules (\mathrm{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 (\mathrm{HCO}). The vibron model, based on the (U(4)) Lie algebras, has then been applied for the calculation of the vibrational spectra of the (\mathrm{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.
