Mechanisms of Raman scattering spectrum of light from pyridine molecule in the lower frequency range
The laws of interaction of electromagnetic wave radiation with pyridine molecules and atoms were studied using Raman light scattering spectra of light, and it was shown that the spectra appearing in the lower frequency range (0 ÷ 1031 cm−1) are related to the rotational-rocking movement of molecules. Based on quantum-chemical calculations, a structural model of the pyridine molecule was created. The possibility of determining the bond lengths and angles between the atoms in the pyridine molecule was suggested. Based on the obtained results, the frequency values of the Raman scattering spectra of light from the pyridine molecule were determined by theoretical calculations and compared with the experimental results. Based on the analysis of the results of the research, it was found that the intensity of the Raman scattering spectrum of the light generated by the rotational-rocking laws of the pyridine molecule is significantly smaller than the intensity of the spectra corresponding to other frequencies.
