Abstract

Gas chromatography-Fourier transform infrared spectroscopy (GC/IR) was used to analyze a series of alkyl nitrites (butyl and pentyl) as well as some typical “street products” containing alkyl nitrites. The vapor phase IR spectra of the nitrites exhibited strong absorbances near 1665 and 1620 cm^-1 (anti and syn R-O-N = O stretches) and 780 cm^-1 (O-N stretch); yet enough variation exists to distinguish between them. Street samples, or purposely “aged” nitrites, showed mixtures of readily separated components consisting of alkyl nitrites and nitrous oxide.
