通过分析其荧光光谱发现具有激基缔合物荧光发射的所有特征，认为处于基态和激发态的团簇分子间形成了激基缔合物。

Through analyzing the fluorescent characteristics of an excimer, it is proposed that the excimers are formed between the ethanol-water cluster molecules in the excited state and in the ground state.

因此，发生第一激发态跃迁时，将发生分子间电子转移，从而引起荧光猝灭效应。

It suggests that intermolecular electron transfer occurs during the transition of the first excited state, which results in the fluorescence quenching effect.
