Infrared spectroscopy

External spectroscopic analysis can be used to study the structure and chemical bonds of molecules, and can also be used as a method to characterize and identify chemical species. The infrared spectrum is highly characteristic and can be analyzed and identified by comparing it with the infrared spectrum of a standard compound.
uses the characteristic wavenumber of chemical bonds to identify the type of compound and can be used for quantitative determination. Due to the interaction of adjacent groups in the molecule, the characteristic wave number of the same group in different molecules has a certain range of variation. In addition, infrared spectroscopy is also widely used in the study of the configuration, conformation, and mechanical properties of polymers, as well as in the fields of physics, astronomy, meteorology, remote sensing, biology, and medicine.
