The index of refraction n-italic and the extinction coefficient k-italic of liquid sulfur in the 0.4--2.0-..mu..m wavelength region were measured at several temperatures between 121 and 183 /sup 0/C. From these data the reflectance R-italic was calculated. These parameters show a change in behavior with increasing temperature. The n-italic vs temperature curves for lambda = 0.4 and 0.45 ..mu..m show an earlier rise with temperature compared with those for longer wavelengths. Results for cooling the liquid from around 180 /sup 0/C reveal an overall difference relative to heating the liquid from 121 /sup 0/C. Values of n-italic for the supercooled liquid down to 85 /sup 0/C are given. A discussion of the results is presented.
