The dispersion of carbon tetrachloride, carbon disulfide, chloroform, cyclohexane, tetrachloroethylene, methylene iodide, acetone, and perfluoro 1,3,5-trimethylcyclohexane has been measured in the 2–15 µ region using an interferometric method. The problem of assigning the proper orders of interference to the observed fringe system has been solved by studying the compounds of interest dissolved in carbon disulfide and carbon tetrachloride. Since the orders of interference can be reliably determined for these two solvents one can follow the shift in order as the concentration of the solute is increased in a stepwise fashion from 0 to 100%.
