摘要：
A single crystal of monoclinic sodium dichromate dihydrate was investigated by FTIR-spectroscopy in the spectral region of 4000-80 cm(-1). On the measured reflection spectra dispersion analysis was performed to gain the oscillator parameters of the transition dipole moments of Na2Cr2O7 center dot 2H(2)O and by that the dielectric tensor function. The gained oscillator parameters were verified by forward-calculation of spectra using different crystal faces. (C) 2018 Elsevier B.V. All rights reserved.
