| Abstract: | Infrared spectroscopy is one of the main techniques in qualitative analysis of chemical compounds. Its primary analytical technique includes transmission spectroscopy, diffuse reflectance spectroscopy, attenuated total reflectance spectroscopy, and so on. In this paper, it is designed to analysis benzoic acid＇s structure by infrared spectroscopy using pressed -disk technique and diffuse reflec- tion respectively with the purpose of updating teaching contents, reforming experimental teaching methods and strengthening students understanding of infrared spectrum analysis method. |
