Dispersion analysis of sodium dichromate dihydrate Na2Cr2O7·2H2O single crystal
in: Spectrochimica Acta Part A-Molecular and Biomolecular Spectroscopy (2018)
A single crystal of monoclinic sodium dichromate di hydrate in principal cut 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 Na2Cr2O7·2H2O and by that the dielectric tensor function. The gained oscillator parameters were verified by forward-calculation of spectra using different crystal faces.
