Lay low for a while : The low‐lying nπ* and ππ* triplet states of substituted acetophenones have been directly observed by time‐resolved near‐infrared spectroscopy. The apparent reactivities of the ππ* T 1 states of acetophenones have been shown to arise from the thermal population of the higher nπ* T 2 states. Thermal equilibrium also occurs between the T 1 and T 2 states of the acetophenones.
