A potential energy surface for \(\mathrm{H}_{3}^{+}\)is determined by adjusting 11 parameters from the ab initio surface of Lie and Frye ( \(J\). Chem. Phys. 96, 6784-6790, 1992) to a data set \(243 \mathrm{H}_{3}^{+}\)energy levels covering vibrational levels up to \(3 v_{2}\) and rotational levels

β¦ Synopsis
A new H3 potential energy hypersurface for arbitrary nuclear arrangements is generated fmm Liu's very accurate (eO.3 kcai/mole error) collinear ab initio calculation and compared with other general geometry surfaces. Preliminary classical trajectory calculations on the new hypersurface are presented and compared with results on the Porter-l&plus surface. * The basic trajectory routine was that written by Muekemmn [30]. see also ref. [3&l,
