利用O2的（0，v '）舒曼-龙格带（B 3 u− <$X 3 g−）的激光诱导荧光探测O3在248 nm光解产生的振动激发O2（X 3 g−，v'= 9，12和15）。初生转动分布都在可用动能的15%处出现尖锐的峰值。与统计模型和脉冲模型的比较表明，能量释放主要是脉冲的。然而，虽然脉冲模型准确地预测了O2（X 3 g−）的转动能量分布，但它并不同时与先前发表的光产物角分布相匹配。
Vibrationally excited O2(X 3Σg−, v‘=9, 12, and 15) produced from the 248 nm photolysis of O3 was probed using laser‐induced fluorescence of the (0,v‘) Schumann–Runge bands of O2(B 3Σu−←X 3Σg−). The nascent rotational distributions are all sharply peaked at 15% of the available kinetic energy. Comparison to statistical and impulsive models of photodissociation suggests that the energy release is largely impulsive. However, while the impulsive model accurately predicts the rotational energy distributions of O2(X 3Σg−), it does not simultaneously match previously published photoproduct angular distributions.
