自从1947年双光束红外光谱仪问世以来,红外光谱法很快就在化学领域里得到广泛的应用,如有机化合物的鉴定,未知化合物的结构研究,官能团分析,有机化学反应的研究等,对有机化学的发展作出了重要的贡献。现在红外光谱法已是公认的重要分析工具之一了。红外光谱法之所以能够取得今天的地位,并不是偶然的,与其他常用的物理方法相比较,它的确具有很多的优点。例如在天然产物的研究中,特别是一些具有生理活性的物质,这些物质往往是极难获得的,而红外光谱测定所需的样品一般只要1—5毫克,甚至更少,而且用后可以回收,此外测定时间也比较短,
Since the advent of dual-beam infrared spectroscopy in 1947, infrared spectroscopy has been widely used in the field of chemistry, such as the identification of organic compounds, structural studies of unknown compounds, functional group analysis, organic chemistry reactions, Has made an important contribution to the development. Infrared spectroscopy is now recognized as one of the important analytical tools. It is not by chance that infrared spectroscopy has achieved its place today, and does have many advantages over other commonly used physical methods. For example, in the study of natural products, especially some physiologically active substances, which are often extremely difficult to obtain, the samples required for the determination of the infrared spectrum generally have only 1-5 mg or less, and can be recovered after use , In addition to measuring time is relatively short,
