Abstract
WE have recently described1 a method of studying the reactivity of aromatic molecules in their lowest triplet states. For example, the system benzene + nitric oxide, irradiated within the paramagnetically induced2 forbidden T ← S 0 band (λ2900–3400 Å.), reacts, the photochemically active radiation being absorbed neither by nitric oxide nor by benzene alone. The effect is considered as the reaction of benzene, excited to the lowest triplet state, with nitric oxide in its ground-state.
