CALCULATIONS FOR THE VIBRATION-ROTATION LEVELS OF H-2(+) IN ITS GROUND AND FIRST EXCITED ELECTRONIC STATES

Non-adiabatic dissociation energies are calculated for 462 vibration-r otation levels of the ground electronic state of H-2(+), together with the three vibration-rotation levels of the first excited electronic s tate, using a transformed Hamiltonian and an artificial-channels scatt ering method. Coupling of rotational and electronic angular momenta is accounted for, so that ground state levels with the highest N are inc luded. Relativistic and radiative corrections are made to give dissoci ation energies, that of the 0,0 level of the ground electronic state a greeing with experiment. In particular, calculated energy separations are in excellent agreement with the few available experimental values.
