摘要:
The influence of an initial excitation of a molecular vibrational mode on the photofragmentation process occurring in fragmentation processes in the fields of two lasers (IR + UV) is investigated theoretically. The problem is treated as a modified Franck-Condon transition into the continuum. The calculations indicate that an initial vibrational excitation can lead to higher fragmentation probabilities in agreement with experimental results.
