State Dissociation

Vibrational predissociation (VP) of glyoxal complexes formed in a supersonic expansion, has been studied in several vibrational levels of the first excited singlet electronic state S1(1Au) of glyoxal. Light complexes as H2-glyoxal display a nice state to state dissociation. Whereas the analysis of the fluorescence spectrum, together with lifetime measurements, have shown that VP is in competition with other intramolecular vibrational energy redistribution processes in these systems, as well as inter-system crossing (ISC). Glyoxal-Ar and glyoxal-Kr behave very similarly. In particular, two isomers exist with different dissociation schemes (but similar for the same isomer of Ar or Kr-complex), and Kr does not seem to enhance ISC. Thus selectivity in the dissociation routes has to be understood as a competition between these deactivation channels.

The competition between multiple pathways sampled during the energetic relaxation of excited molecules can be difficult to experimentally decipher. The rare gas···dihalogen van der Waals complexes have remained key systems...
