偏振光在电子光谱学中不仅用于获得关于吸收和发光带的位置、强度和精细结构的信息，这些信息可以通过溶液的正常电子光谱学获得，而且还用于确定与分子骨架有关的跃迁矩的取向。本文简述了分子光学各向异性的理论和实验原理，并详细讨论了三种最成功的方法（分子在薄膜和晶体中机械取向后的光谱法，或在溶液中电取向后的光谱法，以及固溶体的发光偏振法），并用典型例子加以说明。在发光偏振方面，特别强调三重态-单重态磷光。参考了生物化学中液体溶液的极化测量的重要性（通过测量旋转弛豫时间研究大分子的分子间相互作用）。
Polarized light is used in electronic spectroscopy not only to obtain information about the positions, intensities, and fine structures of absorption and luminescence bands, which can be obtained by normal electronic spectroscopy of solutions, but also to determine the orientation of the transition moments in relation to the molecular framework. The theoretical and experimental principles of molecular optical anisotropy are briefly described, and the three most successful methods (spectroscopy after mechanical alignment of the molecules on films and in crystals, or after electrical alignment in solution, and luminescence polarization of solid solutions) are discussed in detail and illustrated by typical examples. In connection with luminescence polarization, special emphasis is placed on triplet-singlet phosphorescence. Reference is made to the importance of polarization measurements on liquid solutions in biochemistry (study of intermolecular interactions of macromolecules by measurement of the rotational relaxation times).
