Chemiluminescence from Al+O/sub 3/: perturbations, populations, and vibrational analysis for the AlO A/sup 2/. pi. --X/sup 2/. sigma. /sup +/ transition
The A/sup 2/Pi/sub i/ -- X/sup 2/..sigma../sup +/ chemiluminescence resulting from the reaction Al + O/sub 3/ ..-->.. AlO* + O/sub 2/ was investigated. It was found that the constants extracted for the A/sup 2/Pi/sub i/ state by McDonald and Innes adequately describe the vibrational structure of this state to high (approx.29) vibrational levels, the behavior being indicative of a Morse oscillator. Perturbations previously observed in the X/sup 2/..sigma../sup +/ state are explicitly analyzed in terms of A/sup 2/Pi/sub /sup 1///sub 2// -- X/sup 2/..sigma../sup +/ spin--orbit interactions, and a comparison with A/sup 2/Pi/sub /sup 1///sub 2// -- B/sup 2/..sigma../sup +/ perturbations is made. Approximate populations N/sub v'/ for the A/sup 2/Pi/sub i/ vibrational levels are determined; the population distribution is dramatically non-Boltzmann, peaking at an energy just below that corresponding to the v = O level of the B/sup 2/..sigma../sup +/ state. This peaking is explained in terms of efficient collisional transfer from the A state to the B state. 6 figures, 1 table.
