Abstract
This paper describes the study of two alkaloids extracted from
Pilocarpus Microphyllus (Rutaceae): pilosine and epiisopilosine. These
substances have potential application in the treatment of several
diseases. In this work FT-Raman and the FT-IR spectra of pilosine and
epiisopilosine were investigated at 300 K. Vibrational wavenumber and
wave vector have been predicted using density functional theory (B3LYP)
calculations with the 6-31 G(d, p) basis set. A comparison with
experiment, allowed us to assign most of the normal modes of the
crystals.
