一、前言拉曼光谱法是与红外光谱法相互补充的分析方法,很早就是分析化学工作者的有效工具,不过由于当时没有高强度的单色激发光源,在很长时间里这方面的工作进展较小,但是60年代初激光的出现,却给拉曼光谱带来了新的生命。激光的高单色性、高亮度、高度的方向性及偏振特性,使它立即成为拉曼光谱的理想光源。从事这方面的研究工作极为活跃,样品用量已可缩减至几毫微升,有的工作可在百分之几秒的时间内记录下全部谱图,气体、
I. Introduction Raman spectroscopy is an analytical method that complements infrared spectroscopy. It was an effective tool for analyzing chemical workers long ago, but due to the lack of high-intensity monochromatic excitation light sources at the time, work in this area for a long time Little progress has been made, but the advent of lasers in the early 1960s brought new life to Raman spectroscopy. The high monochromatic, high brightness, high directivity and polarization characteristics of a laser make it an ideal source for Raman spectroscopy immediately. In this area of research work is extremely active, the sample dosage can be reduced to a few nanoliters, and some work can be recorded in a few seconds seconds of all the spectra, gas,
