【摘要】 讨论了旋光性对Raman散射的影响。在α-石英晶体中获得了消除旋光影响的纯Raman谱,在此基础上,讨论了α-石英晶体(单轴晶体)的Raman谱中,x轴和y轴的非等价性问题,以及与这种非等价性相应的振动模的对称性。更多还原

【Abstract】 The influence of optical activity on Raman scattering is discussed. Some pure Raman spectra of a-quartz with this effect eliminated have been obtained. Based on these results the nonequivalence between x and y axes in Raman spectra of the unia-xial a-quartz under some scattering geometries has been analyzed.更多还原
