The Raman scattering of a molecule is generated by interactions of its electrons with incident light. The electric vector of the Raman scattered light is related to the electric vector of the incident light through a characteristic Raman tensor. A unique Raman tensor exists for each Raman-active molecular vibrational mode. In the case of biologically important macromolecules Raman tensors have been determined for a few hundred vibrational Raman bands. These include proteins and their amino acid constituents, as well as nucleic acids (DNA and RNA) and their nucleotide constituents. In this review Raman tensors for 39 representative vibrational Raman bands of biological molecules are considered. We present details of the Raman tensor determinations and discuss their application in structural studies of filamentous bacteriophages (fd, Pf1, Pf3 and PH75), fowl feather rachis and eyespots of the protists, Chlamydomonas and Euglena.
分子的拉曼散射是由其电子与入射光相互作用产生的。拉曼散射光的电矢量通过特征拉曼张量与入射光的电矢量相关。每个拉曼活性分子振动模式都存在一个独特的拉曼张量。对于具有生物学重要性的大分子，已经确定了数百个振动拉曼带的拉曼张量。这些包括蛋白质及其氨基酸成分，以及核酸（DNA和RNA）及其核苷酸成分。在本综述中，考虑了生物分子39个代表性振动拉曼带的拉曼张量。我们介绍了拉曼张量测定的细节，并讨论了它们在丝状噬菌体（fd、Pf1、Pf3和PH75）、家禽羽毛轴和原生生物衣藻和眼虫的眼点结构研究中的应用。
