一、引言目前在我国红外光谱分析法已成为仪器分析的重要组成部分,是科学研究、生产、环保、外贸等不可缺少的分析手段。特别在化学工业上应用更为广泛。加对产品或原材料的分析与鉴定,确定物质的化学组成和化学结构,检查样品的纯度。红外光谱分析法具有快速、可靠、用量少且不破坏样品等优点。红外光谱有两个重要特点 a)任何一类化学基团,不论它是存在于哪种化合物中,它在红外光谱中出现的特
I. INTRODUCTION At present, infrared spectroscopy in our country has become an important part of instrumental analysis and an indispensable analytical tool for scientific research, production, environmental protection and foreign trade. Especially in the chemical industry is more widely used. Plus product or raw material analysis and identification, determine the chemical composition and chemical structure of the material, check the purity of the sample. Infrared spectroscopy has the advantages of fast, reliable, less dosage and does not damage the sample. Infrared spectroscopy has two important characteristics: a) Any type of chemical group, regardless of which compound it is present in, and its presence in the infrared spectrum
