Through analyzing the fluorescentcharacteristics 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.
Furthermore, a new method to distinguish methanol and ethanol is put forward by the spectra characteristics in longest absorption wavelengths and center fluorescent wavelength.
并由此提出了用最长吸收波长和荧光光谱中心位置的光谱特性有效区分甲醇和乙醇分子的方法。

By using lanthanide ions, especially europium ions as the fluorescent labels of samples, TFFBS can perform time resolved fluorescence detection from spectral characteristics of europium ions.
