摘要

红外光谱仪是鉴别物质和分析物质结构的有效手段,其中傅立叶变换红外光谱仪(FT-IR)是七十年代发展起来的第三代红外光谱仪的典型代表。它是根据光的相干性原理设计的,是一种干涉型光谱仪,具有优良的特性,完善的功能,并且应用范围极其广泛,同样也有着广泛的发展前景。本文就傅立叶变换红外光谱仪的基本原理作扼要的介绍,总结了傅立叶变换红外光谱法的主要特点,综述了其在各个方面的应用,并对傅立叶变换红外光谱仪的发展方向提出了一些基本观点。

关键词傅立叶变换红外光谱仪;基本原理;应用;发展

Abstract

Infrared spectroscopy is an effective method to identify substance and analyze the structures of molecular. Fourier transform infrared (FT-IR) spectrometers developed in the seventies are a typical representative of the third generation of infrared spectroscopy. They are a kind of interference-type spectrometers which were designed based on the principle of coherent light, with excellent features and perfect functions. And they haven’t only been used widely but also have extensive prospects. In this paper, the basic principles of Fourier transform infrared spectrometer are described briefly. The main features of FT-IR were summed up as well as its application in various fields, and some basic opinions of developmental direction as far as FT-IR were put forward.

Key words: Fourier transform infrared spectrometer Basic principles Application Development
