Abstract

A model to determine refractive index and the intermolecular force constant in a polymeric chain is presented in this study. We have used the UV/visible absorption spectrum of a sample to determine afore mentioned parameters. The exponential absorption wavelength points of the spectrum are used to determine these parameters, on which the optical band gap of the material is defined. This study is carried out for various dopant concentration of a composite, so as to get a comparative insight. This study reveals the dependence of these parameters on dopant concentration and the wavelength.
