Complete dispersion analysis of single crystal EDDt

We present the first complete dispersion analysis of the organic ethylenediamine-d-tartrate (EDDt) in single crystal form in the spectral range of 5000-100 cm-1. The obtained oscillator parameters were used to generate the polarized and the cross-polarized spectra of randomly oriented polycrystalline EDDt. The comparison of the generated with the experimental spectra confirm the value of obtained oscillator parameters and dielectric tensor function.
