摘要

利用拉曼光散射光谱研究了电磁波辐射与吡啶分子和原子的相互作用规律,结果表明,出现在较低频率范围(0 ÷ 1031 cm-1)的光谱与分子的旋转摇摆运动有关。根据量子化学计算,建立了吡啶分子的结构模型。提出了确定吡啶分子中原子间的键长和角度的可能性。根据所获得的结果,通过理论计算确定了吡啶分子光的拉曼散射光谱的频率值,并与实验结果进行了比较。根据对研究结果的分析,发现由吡啶分子的旋转摇摆规律产生的光的拉曼散射光谱强度明显小于其他频率对应的光谱强度。

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.
