A Generalized Approach to the Calculation of Ro-vibrational Spectra of Triatomic Molecules

A generalization of the well known atom-diatom scattering hamiltonian to a coordinate system of two lengths and an angle is derived, another special case of which is a previously known bond angle-bond length hamiltonian. Different axis embeddings are also considered. The formalism is applied to the ro-vibrational levels of D2 H+, CH~ and HDHe (A 1A') and… (More)
