“…This approach has been actively exploited in studying the CINAT from the first-tier IP state E0 g + of molecular iodine with various partners in a number of experimental [10][11][12][13][14][15][16][17][18] and theoretical [19][20][21] works ͑we do not discuss here early lowresolution studies devoted mainly to I 2 ͑D0 g + ͒ CINATs cited in Refs. 4, 7, and 22͒.…”

Nonadiabatic transitions induced by collisions with He, Ar, Kr, and Xe atoms in the I(2) molecule excited to the f0(g)(+) second-tier ion-pair state are investigated by means of the optical-optical double resonance spectroscopy. Fluorescence spectra reveal that the transition to the F0(u)(+) state is a dominant nonradiative decay channel for f state in He, Ar, and Kr, whereas the reactive quenching is more efficient for collisions with Xe atom. Total rate constants and vibrational product state distributions for the f-->F electronic energy transfer are determined and analyzed in terms of energy gaps and Franck-Condon factors for the combining vibronic levels at initial vibrational excitations v(f)=8, 10, 14, and 17. Quantum scattering calculations are performed for collisions with He and Ar atoms, implementing a combination of the diatomics-in-molecule and long-range perturbation theories to evaluate diabatic PESs and coupling matrix elements. Calculated rate constants and vibrational product state distributions agree well with the measured ones, especially in case of Ar. Qualitative comparison is made with the previous results for the second-tier f0(g)(+)-->F0(u)(+) transition in collisions with I(2)(X) molecule and the first-tier E0(g)(+)-->D0(u)(+) transition induced by collisions with the rare gas atoms.

CO2 isolated line shapes by classical molecular dynamics simulations: Influence of the intermolecular potential and comparison with new measurementsWe use three-dimensional classical molecular dynamics to simulate femtosecond time-resolved experiments on the caging dynamics of I 2 in rare gas environments ͓Wan et al., J. Chem. Phys. 106, 4353 ͑1997͔͒. The calculated pump-probe signals are in excellent agreement with experiment. Prominent oscillatory structures as observed in the pump-probe signals are interpreted in terms of caustics which appear in the classical bound state dynamics of the caged molecules. The results confirm conclusions based on a simple statistical model which treats the collisions as random perturbations involving hard sphere scattering.
