Abstract：By using equipment of UV-240 ultra-violet spectrophotometer and Sp-2558 multifunctional spectrometer system, the UV-light absorption spectra and the fluorescence spectra of propanol and isopropanol，as well as their comparison were studied. According to the results, propanol and isopropanol can be clearly distinguished with absorption spectra and fluorescence spectra. The reasons for difference spectra of the two liquids were also explained. Moreover, the fluorescence spectra of the four kinds of difference alcohol were compared and the results were discussed. The whole research outcomes will provide a new method for effective measurement of different alcohol, and also produce some valuable theoretical references to the calculation of quantum chemistry.
