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.
