Heroin and three structurally related isomers were studied. The configurational assignments of the structural isomers supported from nuclear magnetic resonance and mass spectrometry data are discussed. Infrared spectroscopy spectra are also presented. Gas chromatography procedures using packed and capillary systems demonstrated how the isomers could be best fully resolved.
