2021-08-26 06:50 Infrared spectroscopy is a kind of absorption spectroscopy, which is mainly used to study the vibrational and rotational spectra of molecules. It is generally used to study the structure of polyatomic molecules, and molecular quantitative and qualitative analysis. Infrared spectroscopy is usually expressed as a band spectrum and is related to the vibrational energy level of molecules. Different configuration molecules show different infrared spectroscopy images. Therefore, it is a powerful tool to determine molecular configuration, and it is very simple and accurate to use.
