摘要
在 qcω条件下,得到了极性声子频率色散关系的简化形式。将此结果应用于 TGS 晶体,修正了 Tashiro 等人的计算结果,并与红外谱的实验结果比较,基本吻合。
Under the condition of qc>>ω,the simplified form of frequency dispersion relation for polar phonons is obtained and applied to TGS single crystals.The Raman data of Tashiro are analysed by our method,so they agree with the IR results well.
