Infrared reflection spectra of the ordinary and extraordinary rays of single crystal ferric oxide alpha Fe2O3 in the form of the mineral hematite are isolated and measured. Dispersion analyses are performed on these spectra and the bestfit resonance parameters are identified, along with estimated tolerances. Longitudinal optical mode frequencies are calculated from these data. Also calculated are refractive index, extinction coefficient, absorption coefficient, and real and imaginary parts of the dielectric constant of both rays.
