The authors report herein investigation of the photochemistry of 4-(dimethylamido)phenyl azide at room temperature in fluid solution by transient absorption techniques with detection by infrared and ultraviolet spectroscopy. These experiments establish with certainty the intermediacy of 5-(dimethylamido)-1,2-dehydroazepine, identify it as the species trapped by nucleophiles, permit the estimation of
