We introduce an algebraic model of coupled anharmonic benders capable of describing the complete spectrum and intensities of bending vibrations of medium size and large polyatomic molecules. We apply this model to the calculation of C-H bends in CsH6. The model appears to describe the data well.

Even when a simple valence force field is used to represent the bound state normal modes, the kinetic energy operator couples bending and stretching motions in bent triatomic molecules. These bend-stretch couplings have been ignored in previous theoretical descriptions of photodissociation and are s

The vibrational excitations of ozone, including both bending and stretching vibrations, are studied in the framework of a symmetry-adapted algebraic approach. This method is based on the isomorphism between the U( 2) algebra and the one-dimensional Morse oscillator, and the introduction of point gro
