| Abstract: | Formula and theoritical curve of polarized Raman scattering intensity from LB film have been de-
duced, in relation with the incident, scattering angles of light and the oriented angle of ordered molecules packing
in the LB film. It is proposed that the oriented angle of molecules can ne determined by measureing the angle distribu-
tion of polarized Raman scattering and fitting it with the theoritical formula. |
