Energetics of the Photodissociation of Polyatomic Molecules

摘要: We present a quantum mechanical theory of the decomposition processes polyatomic molecules, an important relaxation channel for electronically or thermally excited molecular systems. Both direct photodissociation and weak predissociation are described from unified standpoint. An essential feature molecule dissociation is fact that excess energy may be partitioned among vibrational rotational degrees freedom in addition to electronic translational ones which only accessible diatomic dissociations. The central focus is, therefore, on description vibrational, translational, rotational, etc. distributions fragments factors, such as bound dissociative potential surfaces, excitation wavelength, etc., influencing these distributions. describes both sudden Franck-Condon process, leading transition state, half-collision wherein mutually interact while they recede each other surface.
