The quenching effect of anhannonicity on the inter-bond coupling and Coriolis interaction is studied. The local to normal mode correlation diagrams for XY2 and XYJ stretching overtones up to ~60 and 20, respectively, are calculated in the normal mode model with Darling-Dennison resonances included.

An algebraic approach to describe the vibrational excitations of molecules is presented. The model is established in a local mode scheme and involves an anharmonization procedure in which the local harmonic oscillators associated to each internal degree of freedom are substituted by Morse oscillator

A U(2) algebraic model is presented to describe stretching vibrations of XY n (n Ο­ 2, 3, and 4) systems, where anharmonic interactions between the bond modes are considered. This model in a limit corresponds to an anharmonically coupled local-mode model. As an example, the model for a molecule XY 4
