Abstract

The spectral intensity of Raman scattering in quartz crystals has been calculated in a wide temperature range including the point of the α–β phase transition. It is established that a central peak is present in the scattered radiation spectrum at different temperatures with allowance for the interaction between the fundamental soft mode and an additional low-frequency oscillator. The intensity and half-width of the central peak are calculateed in a wide temperature range.

宽温度范围内石英晶体拉曼光谱的中心峰

摘要

石英晶体中拉曼散射的光谱强度已在包括α-β相变点在内的较宽温度范围内进行了计算。可以确定，在不同温度下，在散射辐射光谱中会出现一个中心峰，并考虑到了基本软模与附加低频振荡器之间的相互作用。在较宽的温度范围内计算中心峰的强度和半峰宽。
