Joint Rotational Analysis of 24 Bands of the H2Se Molecule

A global fit of all currently available rotation-vibration energies has been made for 24 vibrational states of the H802Se molecule. The resulting set of 112 parameters reproduces the initial 3516 vibration-rotation energies with a mean accuracy of 10.6 x 10(-3) cm-1. Using this model as a starting point, the rotational fine structure of the extremely weak local mode bands (13(+); 1)/(13(-); 1) and (06(+); 0)/(06(-); 0) could be analyzed; the results are discussed.
