【摘要】 采用UV-240紫外分光光度计及Sp-2558多功能光谱测量系统,研究了正丙醇、异丙醇的紫外吸收光谱及荧光光谱,并对它们进行了比较。研究结果表明,使用紫外吸收光谱和荧光光谱很容易鉴别正丙醇与异丙醇,同时也对正丙醇与异丙醇间光谱有差异的原因做出了解释。并进而对甲醇、乙醇、正丙醇与异丙醇4类醇类物质的光谱进行了对照研究,研究结果为醇类物质的识别提供了一种新而有效的测量方法,对量子化学计算也有理论上的参考价值。

【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.
