标题： Analysis of the SEHR Spectra of Symmetrical Molecules on the Base of the Dipole-Quadrupole Theory

摘要： 本文基于偶极-四极SEHRS理论分析了对称分子的SEHR光谱。 展示了由对应对称群的单位不可约表示变换的振动引起的带的存在。 根据理论群分析，这些带在吩嗪、吡嗪以及属于许多群（例如Cnh、D和更高对称群）的分子中的常规HRS中是禁戒的。 它们的出现强烈证实了偶极-四极SEHRS理论，该理论也能够解释这些分子SEHR光谱的其他特征。 对吡啶和结晶紫的SEHR光谱的研究表明，它们也可以用该理论来解释。 所有这些结果表明存在强四极光-分子相互作用，这是表面增强光学过程的原因。 显示英文摘要

摘要： The paper analyses the SEHR spectra of symmetrical molecules on the base of the dipole-quadrupole SEHRS theory. Existence of the bands, caused by vibrations transforming after the unit irreducible representations of corresponding symmetry groups is demonstrated. As it follows from the theoretical group analysis, these bands are forbidden in phenazine, pyrazine and in usual HRS in molecules belonging to a large number of groups (Cnh, D and higher symmetry groups for example). Their appearance strongly confirms the dipole-quadrupole SEHRS theory, which is able to explain other features of the SEHR spectra of these molecules also. Investigation of the SEHR spectra of pyridine and crystal violet demonstrates that they can be explained by this theory too. All these results point out the existence of the strong quadrupole light-molecule interaction, which is the reason of surface-enhanced optical processes.
