Abstract
Ab-initio calculations for low-lying states of H3 in C2v and D∞h symmetry are reported. It is shown that the potential energy surfaces of some states dissociating to H2(X, 1Σg +) and H (n = 2) possess deep minima in D3h symmetry. The results are used to discuss recent experiments on the reaction of H2 with metastable H.
