✦ Synopsis

The rotation-vibration spectra of diatomic molecules are discussed with the aid of the SO ( 2.1) dynamic group. The eigenvector of the compact generator is explicitly obtained by realizing the generators in the four-dimensional polar coordinates. A special representation of the radial part of the generators allows us to describe the discrete and continuous states of the Morse oscillator,

The results of some highly accurate non-empirical ro-vibrational calculations on H 2D~are reported including some for J 30 which are the first calculations to describe such a highly rotationally excited state. These results are obtained using an improved version of our algorithm. The method used is
