| As shown in Fig4,following the decrease of ¦Â-carotene concentration in CS2 ,the electron delocalization will make the more narrow Electronic transition bandwidth. From the equation (4),it is inversely proportional relationship between the the damping factor i and the Raman polarizability tensor.The smaller i ,the larger the Raman polarizability tensor,and corresponding Raman intensity of molecules increases,which lead greatly high Raman cross section. |
