比较了7-氮杂吲哚及其A-甲基衍生物的光谱性质。研究了温度对7-氮杂吲哚浓溶液荧光的影响。这些结果为7-氮杂吲哚氢键二聚体在最低激发单重电子态发生分子间双质子转移反应提供了有力的支持。看来，在非常低的温度下，质子隧穿可能是反应的一个重要机制。
The spectral properties of 7-azaindole are compared with those of its A-methyl derivatives. The effect of temperature on the fluorescence of a concentrated solution of 7-azaindole is alsoinvestigated. The results offer strong support for the occurrence of an intermolecular double proton-transfer reaction in the lowest excited singlet electronic state of 7-azaindole hydrogen-bonded dimers. It appears that, at very low temperatures, proton tunneling may be an important mechanism for the reaction.
