摘要	We have determined the Raman scattering cross sections(RSCSs) of beta-carotene for C=C and C-C stretching modes, with the 1444 cm(-1) Raman band of cyclohexane as internal standard, in different solvents at low concentrations by measuring Raman intensity. The results show that RSCSs of beta-carotene were 10(6)-10(7) times larger than the general RSCSs, we analyzed that this enhancement was caused not only by the resonance Raman effect but also by nonlinear coherent CC vibration in aqueous beta-carotene. Moreover, overtone and combinations of it were also observed and their intensities were 10%-20% of those of their fundamentals when beta-carotene was dissolved in non-polar solvents, respectively.
