Abstract

Reflection spectra of opaque samples recorded at different angles of incidence and for both polarizations were used to evaluate the optical constants. A subsequent classical oscillator fitting analysis of these spectra provided the dispersion of the refractive index and the absorption index for cuprous ethyl and butyl xanthate complexes across the midinfrared region. The advantages of recording spectra under certain conditions are discussed.
