State-specific experiments were performed which studied collision induced electronic transitions (CIET) in a diatomic molecule. These optical- optical double resonance (OODR) experiments employed a resonance enhanced multiphoton ionization (REMPI) technique for purposes of detection. A strong dependence on Franck-Condon factor (FCF) and small energy gap, as well as a propensity for conservation of rotational angular momentum have become trademarks of our CIET experiments. Present theoretical models of these processes are ...
Electronically excited metastable diatomics are energy rich 1, 2, and are known to play an important role in the chemistry of normal and perturbed atmospheres. The dynamics of these species includes both chemical reactivity and collisional energy transfer
Recent work in our laboratory has concentrated on the kinetics of metastable molecular nitrogen, N2(A 3 sigma (+) sub u). Investigations have included measuring v-level specific bimolecular rate constants for the reactions of N2(A, < or = 6) with relatively efficient electronic quenchers (02, NO, CO, N2O, and C2H4) and inefficient electronic quenchers (CH4 and CF4). The latter set of quenchers has provided information on the relative N2(A, v) population ...
