A generalized spherical harmonics expanded orientation distribution function (ODF) has been used to study the orientation of SWNTs. A relationship between the second-and fourth-order SWNT orientation parameters and the Raman scattering intensity and depolarization ratio has been established. Only by
## Abstract Realβtime polarized Raman spectroscopy was used in this study to measure the molecular orientation evolution during blown film extrusion of lowβdensity polyethylene (LDPE). Spectra were obtained at different locations along the blown film line, starting from the molten state near the di
