| Abstract: | Using liquid-core optical fiber, the Raman spectra can be enhanced 10~2~10~3 times. The Raman spectra of CCl_4 in CS_2 and C_6H_5Br are measured by the liquid-core optical fiber, and the measurement accuracy is increased. The experimental results show that as concentration becomes lower, the intensity of the 459 cm~ -1 , 314 cm~ -1 , 218 cm~ -1 Raman lines of CCl_4 is enhanced. The solvent effect is tested and verified accurately. |
