Abstract

The dissociation of a diatomic molecule in low frequency polychromatic fields of moderate intensities is studied. Genetic Algorithm is invoked to search out a set of four optimal non-resonant frequencies (ω 1 - ω 4), intensities (ε14) the and phase angles (δ1 - δ 4), for achieving a facile photo dissociation. Time-dependent Hellmann-Feynman theorem is used to gain insight into the frequency resolved energy absorption pattern. The 'quantum phase space' structures indicate occurrence of bond breaking dynamics akin to the classical one.
