Abstract

By means of IR spectroscopy and X-ray diffractometry, two commercial brands of barbital and four barbital substances recrystallized from water or an acetonewater mixture were examined for polymorphism. The results obtained demonstrate that these substances differ in crystal lattice and that there are six polymorphic modifications.
