The Raman-UV adsorption spectrum of chain-like polyene biological molecule canthaxanthin in cyclohexane was measured. It was found by the study of this spectrum that 1) the transition shows Einstein shift compared with common spectrum 2) the strength of carbon-carbon bond and frequency multiplication of Raman spectrum can reach 30 % that of the baseband and 3) the  Raman scattering cross section of this molecule is large than ordinary ones by six orders of magnitude. Furthermore, the results were analyzed by feeble damped vibration model.
