We present the first successful dispersion analysis of a triclinic crystal in the infrared spectral region. The corresponding scheme involves the parallel evaluation of 12 polarized reflection spectra recorded from three mutual perpendicular faces of a cube-shaped crystal. The dispersion analysis was carried out on a CuSO4 center dot 5H(2)O single crystal. The determined oscillator parameters and the corresponding dielectric function tensor were used to model the spectra of polycrystalline CuSO4 center dot 5H(2)O. The good correspondence between modeled and experimental spectra of the polycrystalline species proves the correctness of the approach. (C) 2013 Elsevier B.V. All rights reserved.
