摘要：

Femtosecond reaction dynamics of Rydberg states (6p 2E1/2 and 7s 2E3/2) in methyl iodide are reported. The observed ultrafast decay and the large isotope effect reflect the Rydberg-valence potentials crossing to yield CH3 + I. The dependence of the dynamics on the vibrational mode is studied with focus on the character of the mode and the coherent coupling. Molecular quantum dynamics simulations are also reported.
