Problems solved by technology

However, since the vibrational transition of molecules is often accompanied by rotational transitions, the vibrational spectrum is banded, and different spectral bandwidths are different, causing errors in the analysis of molecular groups, coupled with the effects of molecular coupling effects and space effects. Therefore, it is necessary to improve the existing molecular group band analysis technology

Description

technical field [0001] The invention relates to the field of group band analysis, in particular to a compound molecular group band analyzer. Background technique [0002] The group band analysis technology mainly uses infrared rays of different wavelengths to irradiate the molecules of the substance, and certain infrared rays of specific wavelengths are absorbed to form the infrared absorption spectrum of this molecule. Each molecule has a unique infrared absorption spectrum determined by its composition and structure, based on which the molecular structure can be analyzed and identified. Infrared absorption spectrum is generated by the continuous vibration and rotation of molecules. Molecular vibration refers to the relative movement of atoms in the molecule near the equilibrium position. Polyatomic molecules can form a variety of vibration patterns. When each atom in the molecule performs simple harmonic vibration near the equilibrium position with the same frequency and ...
