Abstract: | The IR spectra of the real n(ν) and imaginary κ(ν) parts of the complex refractive index of an industrial high-pressure polyethylene film are measured by the methods of transmission and attenuated total reflectance spectroscopy in the range 700–750 cm?1 taking into account the anisotropy and the structural inhomogeneity of the film over its thickness. It is proposed to use these spectra as the reference spectra for polyethylene films in the range around 720 cm?1. |
