摘要：

In this study, a Kramers-Kronig (KK) analysis program has been compiled. The use of the KK method to analyze the normal incidence infrared (IR) reflectance spectra with a single resonance has also been described. To verify our program, spectra generated by a damped single harmonic oscillator model were analyzed, in which the optical parameters were known. Our results show that, the values of optical phonon modes, i.e. w(TO) and w(LO), obtained by this computational technique are in good agreement with the values used in the simulation model. The average errors are sufficiently small, i.e. about 0.67% and 0.25% for w(TO) and w(LO) respectively.
