摘要：

Raman scattering has been studied on one kind of carbon whiskers. The G' band, overtone of D band, is the most intense of all bands-its intensity is up to ten times stronger than that of the G band. Such phenomena can be observed with different excitation wavelength. The strong intensity of the G' band may be related to the disclination existing in the whiskers. Polarized Raman spectra are obtained from the edge plane of the whiskers. The intensity of G' bands obtained with polarized light parallel to carbon layers (Eperpendicular toc) is ten times as strong as that with polarized light normal to carbon layers (Eparallel toc).
