An imaginary complex refraction index (extinction coefficient) has been deduced for a number of common pharmaceutical forms from their specular reflection spectra.

Abstract
An imaginary complex refraction index (extinction coefficient) has been deduced for a number of common pharmaceutical forms from their specular reflection spectra. It seems that reflectivity technique is preferred to the transmission one in those special case in which non-destructive analysis of samples is requested. Furthermore, the obtained results are independent of solvent effects and sample thickness.File in questo prodotto:
