Abstract
The optical crystallographic or microcrystalline properties of the diliturate derivatives (5-nitrobarbituric acid) of the most used psychedelic amphetamine drugs have been determined. The crystallographic properties, especially the orthographic projection drawings and photomicrography of the crystals and other optical crystallographic data, such as the indices of refraction, extinction angles, and optical orientations serve to characterize and identify this group of drug chemicals. These data can be used with ultraviolet-infrared (UV-IR) spectroscopy, thin-layer chromatography and gas-liquid chromatography/mass spectrometry (GLC/MS) data for the identification and confirmation of psychedelic amphetamine drugs.
