The vibrational description of H216O in terms of Morse local oscillators for both bending and
stretching degrees of freedom is presented. Expansions of the kinetic and potential energies …

The efficiency and insight of global, polyad-based modeling in overtone spectroscopy and
dynamics is demonstrated. Both vibration and vibration–rotation polyads are considered …

Emission spectra obtained from jet-cooled disulfur monoxide (S 2 O) molecules have been
interpreted by means of a novel Lie algebraic formalism that makes possible the facile …

The SU (2) vibron model has been shown to correspond to an approximation where only the
dominant Δv=±1 interaction between Morse oscillators is taken into account [A. Frank, R …

The carbon dioxide Raman spectrum is simulated within an algebraic approach based on
curvilinear coordinates in a local representation. The two main advantages of the present …

In this paper, we consider the one-dimensional anharmonic oscillator, which represents well
the anharmonic vibrations in diatomic molecules. For the description of the associate …

We show that the SU (2) vibron model automatically gives the correct coupling between
Morse oscillators as long as they only interact via the dominant Δv=±1 selection rule. We …

This paper is the first to demonstrate the application of U (2) Lie algebraic Hamiltonian in
reproducing and predicting the vibrational energy levels of an asymmetric penta-atomic …

We use a one-dimensional U (2) Lie algebraic model to study fundamental and first-
overtone vibrational frequencies, as well as their combination bands for cyclobutane-d8 …
