Abstract
We have determined the frequency dispersion of the anisotropic complex optical constants of highly stretch-oriented poly(p-phenylene-vinylene) chains from Kramers-Kronig transformation of polarized near-normal-incidence absolute reflectivity data, inversion of polarized reflectance and transmittance measurements, and spectroscopic ellipsometry. The spectroscopic data are discussed in comparison to the results provided by correlated quantum-chemical calculations. On this basis, we assign the nature and polarization of the optical transitions in poly(p-phenylene-vinylene) chains.Keywords
