A flash-photolytic investigation was carried out on the hydrogen bonding interaction of triplet 2-naphthol and 1-anthrol with aromatic <I>N</I>-heterocycles such as 4-methylpyridine, quinoline, and benzo[<I>h</I>]quinoline. The deactivation of triplet 2-naphthol and 1-anthrol by aromatic <I>N</I>-heterocycles was found to be due to the hydrogen atom transfer reaction. The relationship between the reactivity and the reduction potential of aromatic <I>N</I>-heterocycles suggests that the electron transfer from the triplet to the quencher is the primary process of the hydrogen atom transfer reaction.
