概要
- 論文の詳細を見る
Raman spectra of various Cdl. polytypes have been measured at liquid Hetemperature. Several folded modes of the E symmetry optical branch have beenobserved in higher polytypes. The dispersion curve of the E symmetry branch inthe [0044 direction has been obtained from the experimental frequencies of thefolded modes. The pressure dependence of the Raman active modes has been alsomeasured. These results are analyzed by using a linear chain model and a po-larizable ton model. The analysis indicates that the long range forces contributelittle to the interlayer forces and that the difference in long range forces as wellas the short range forces among the polytypes is very small.
