The results of Kramers- Kronig analysis of all the reflectivity spectra were reported based on the results of interband optical transitions observed by means of reflectivity measurements of Hg1-xFexS (x=0.01, 0.04 and 0.06) crystals in the energy range 1.5–12eV. We used a computer program for Kramers-Kronig analysis to determine the Re and Im spectra. The observed dependence of the positions of the spectral peaks on the Fe content allows us to estimate the contribution of Fe-derived states to the band structure of -HgS semiconductor. The interpretation of structures spectra as a result of interband transitions between occupied valence bands and the empty conduction bands are presented along with some conclusions concerning the electronic band structure of -HgS
