一、前言红外截光谱用于解决化学中的问题是近三十年来的事。特别是近十几年来发展更加迅速,因为红外线光谱能解决一般化学和物理方法所难以解决的分析问题,并且大大的节省了研究时间和精力。红外线光谱在化学中的应用一开始就跟国民经济和国防的重大问题联系起来,如对石油分析、解决天然及合成橡胶生产中的化学问题等都起了很大的作用。现在在化学的各个领域中已经广泛地应用着,成为一种不可缺少的日常分析检定方法。早在1800年己经发现红外线现象。红外线是电磁波,它具有光波的一切特性。红外线波长范围的上限是人视觉的极限长波7500(?),而它的下限没有明确的界限,人们常用的是350μ(1μ=10~4(?))。由于实验技术和实用上的习惯,线外线范围通常划分为三段:
I. Introduction Infrared cutoff spectroscopy is used to solve chemical problems in the past three decades. In particular, the development over the past decade has been even faster, because infrared spectroscopy can solve the analytical problems that can not be solved by general chemical and physical methods and greatly save the time and effort of research. The application of infrared spectroscopy to chemistry from the very beginning was linked to the major problems of national economy and national defense, such as the analysis of petroleum and the chemical problems in the production of natural and synthetic rubbers. Now in all areas of chemistry has been widely used, as an indispensable method of routine analysis and verification. As early as 1800, infrared phenomenon has been found. Infrared is electromagnetic waves, it has all the characteristics of light waves. The upper limit of the infrared wavelength range is the human visual limit long wave 7500 (?), And its lower limit is not clearly defined, commonly used is 350μ (1μ = 10 ~ 4 (?)). Due to experimental techniques and practical habits, the outside of the line is usually divided into three sections:
