โœฆ Synopsis

The femtosecond dynamics of a predissociative system is studied by using a quantum time-dependent wavepacket method. The molecular system in this study is loosely based on a Rydberg of methyl iodide. Four electronic states, i.e. the ground state, a Rydberg state optically coupled with the ground state, a dissociative state coupled with the Rydberg state via a non-adiabatic potential, and an ion state optically coupled with the Rydberg state, are included in the calculations. The transients of the methyl iodide ionization signal are calculated for both CHSI and CD& It is found that the deuterated methyl iodide has a longer lifetime due to the mass effect, in agreement with the experiment.

Femtosecond reaction dynamics of Rydberg states (6p 2E,,s and 7s sE,,s) in methyl iodide are reported. The observed ultrafast decay and the large isotope effect reflect the Rydberg-valence potentials crossing to yield CHr t 1. The dependence of the dynamics on the vibrational mode is studied with fo

A model for the dynamics of high Rydberg states in isolated large molecules is proposed. The model accounts for the interaction between the electron and the vibrational degrees of freedom of the core. These are modelled by an Ohmic bath in thermal equilibrium.
