Approach takes advantage of fact that phosphorous oxyfluoride (POF3) and phosphorous oxychloride (POC13) both belong to same molecular symmetry group and should have extinction coefficients that are approximately the same. Extinction coefficient of reagent-grade POC13 is measured, and this coefficient is employed to calculate POF3 concentrations.
