The 10 lysergic and iso-lysergic acid amides described are N,N-dimethyl-, N,N-diethyl-, N-methyl-N-propyl, N-ethyl-N-propyl, and N,N-dipropyl-. Their ultraviolet spectra are insufficiently different for distinction. Mass spectra do not readily differentiate between isomers. Proton magnetic resonance spectra are distinct and provide a positive structural identification of the amide. Their infrared spectra are similar, but suitable for distinguishing these compounds from LSD. Various reference spectra are provided. Thin layer and gas-liquid chromatographic systems suitable for distinguishing these compounds from LSD are described.
