Vibrational Energy Distribution

The vibrational energy distribution in molecules which have quenched O 2 ( 1 ∑ + g ) to O 2 ( 1 ∆ g ) or O 2 ( 1 ∆ g ) to O 2 ( 3 ∑ - g ) is interpreted in terms of the statistical theory. This theory is extended to include cases where initial rotational and translational energy contributes to vibrational excitation of the products. A common linear surprisal plot is observed in the quenching both of O 2 ( 1 ∑) and O 2 ( 1 ∆) by a number of molecules. Strongly inverted vibrational distributions with ⋋ v = - 7.5 are inferred for both products of the quenching step.

Quenching studies have been made in a spherical vessel containing known concentrations of O 2 ( 1 ∆ g ) and O 2 ( 1 ∑ + g ). Rate coefficients for the quenching of O 2 ( 1 ∆ ) by CO and of O 2 ( 1 ∑) by N 2 O, D 2 O, NH 3 , C 3 H 8 , C 2 H 2 , HCl and DCl have been determined. Efficient wall deactivation of O 2 ( 1 ∆) by adsorbed hydrogen halides was observed.
