We strive to extend the anisotropic Raman formalism developed for the transparency regime by us to the absorption spectral range, so that it can be used in the full spectral range of optically anisotropic crystals. Especially the following effects on the polarization dependent Raman scattering will be investigated in detail: The presence of singular optic axis in low symmetry materials, the presence of resonances in the absorption spectral range, the complex-valued Raman tensor and the presence of optical activity.

我们努力将我们为透明区域发展的各向异性拉曼公式推广到吸收光谱范围，这样它就可以应用于光学各向异性晶体的全光谱范围。特别是对偏振相关拉曼散射的影响将被详细研究：低对称性材料中奇异光轴的存在，吸收光谱范围内共振的存在，复值拉曼张量的存在和旋光性的存在。
