The Kramers-Kronig relations can be applied to response functions which satisfy causality. In certain instances they apply to other response functions, for example, the phase and logarithm of the reflectivity. It is easy to compute all the optical constants from the reflectivity data which is measured through a portion of the frequency range by using these relations. A new method for optical data analysis based on expansion in Hermite functions and reasonable extrapolations was employed.(8.9) This method was applied to P-type Sb2Te3. In the Hermite series expansions, 250 terms Were computed. The results of the computation of the optical constants of this material are presented and discussed. A partial and exploratory comparison of the results is made with the electron spectrum(5,6) of isostructural Bi2Te3. The limitations of the analysis are also pointed out.
