Four electronic states of H3 have been studied using a multi-reference configuration interaction method and a basis set of AOs. The calculations were carried out at a fixed bond angle of 60". The four states include the ground state and the Rydberg 2s and 2p, states, as well as the state which in th

โฆ Synopsis
Recent dynamical computations on the LSTH and PK(I1) potential energy surfaces are analyzed in terms of different properties of the surfaces. Differences in the bend level structure of resonances are found to be due to the weaker vibrational force constant at the saddle point of the LSTH surface. The importance of including van der Waals wells in the potential energy surface is demonstrated by analysis of quanta1 resonances in the collinear Mu + DZ reaction.

A 3D time-dependent wavepacket propagation method has been used to study the transition state resonances on the two coupled diabatic states of the H 3 DMBE potential energy surface. We report 14 zero-bend resonances which are found to be in good agreement with the corresponding results calculated us
Unimolecular dissociations of CFaH into (1) CF2(1AI ) + HF, (2) CF 3 + H and (3) CF2H + F were studied by means of RRKM and PST calculations on an ab initio potential energy surface. Activation energies for the three channels (1), ( 2) and (3) are 73.95, 108.20 and 130.02 kcal/mol at G2 level, respe
