Bound ro-vibronic states of triplet H3+

On the basis of a new, highly accurate potential energy hypersurface for the lowest triplet state of H-3(,)+ (3)Sigma (+)(u), the bound ro-vibronic states are calculated for J less than or equal to 5. Since the potential has very shallow minima, those states exist only up to single vibrational excitation. The symmetry properties of the re-vibrational states are investigated. Further, it is demonstrated that the first excited triplet state, which intersects conically with the (3)Sigma (+)(u) state, has no effect on the reported re-vibrational energies.
