A study of the fluorescence lifetimes and quantum yields of 7-azaindole and its methylated derivatives N 1 -methyl-7-azaindole (1M7AI) and 7-methyl-7H-pyrrolo[2,3-b]pyridine (7M7AI) in water is performed in order to explain the observation that the fluorescence spectrum of 7-azaindole apparently consists of one band (λ max =386 nm) whereas in alcohols the spectrum is bimodal (e.g., for methanol, λ max =374, 505 nm)
