In this paper, the effect of temperature on the refractive index of Carbon disulfide liquid based on the influence of temperature on the Sellmeier coefficient has been presented. The effect of temperature on the liquid refractive index of Carbon disulfide in the visible and infrared regions according to the expression of M. Chemnitz was also investigated. From the survey results, it is concluded that as the wavelength increases, the refractive index of Carbon disulfide decreases, but when the temperature is increased then the refractive index of Carbon disulfide decreases faster.
