Abstract
We report results of 5D quantum-dynamical simulations for the vibrational l evels and lifetime of vinylidene. The calculations are based on a new ab in itio potential energy surface and reproduce the observed vibrational struct ure of the photodetachment spectrum very well. The lifetimes thus obtained exceed previous estimates in the literature by 2-3 orders of magnitude. (C) 2000 Elsevier Science B.V. All rights reserved.
