The temperature and frequency dependence of the ultrasonic absorption coefficient in molten selenium have been studied in the range from 200° to 400° C and from 30 to 70 MHz. The data are consistent with the values in the literature for the high‐temperature range but supersede the previous results below 300° C. A theoretical model is prepared in which the monomer (rings) of the selenium represent a nonrelaxing component with the polymer chains forming a relaxing component.
