HORIBA Raman Academy: Orientational Effects on Raman Spectra
This video from Horiba Scientific shows the real-time display of polyethylene and the effects on the Raman spectra of a polyethylene film as a result of stretching. The effects of polymer alignment caused by stretching can be clearly seen in the orientational dependence with respect to the incident polarization of the Raman scattering.
