Introduction. At the present time the Raman spectroscopy is one of the
promising direction in pharmaceutical practice. Raman spectroscopy is the method of
study the vibrational, rotational, and other low-frequency modes of the tested
substance in the range from 100 to 4000 cm`1, based on the phenomenon of inelastic
(Raman) scattering of monochromatic light in the visible, near UV or near-IR.
