摘要：

The Townsend discharge-nitric oxide chemical ionization mass spectra of 27 alcohols (C4-C-7) and 24 alkenes (C-6-C-9) were evaluated regarding their isomeric and congeneric distinction. In alcohols, the ion abundance of major ions such as (M-OH)+, (M-H-3)+ and (M-H-2+NO)+ appearing in their mass spectra were highly dependent on the class of alcohols. Isomeric distinction and selective detection of alcohol were attained by using these characteristic ions. In alkenes, the determination of double-bond positions and the distinction between cis-trans isomers were possible by comparing the intensity ratios of (M+NO-C(n)H2n)+/(M-H) +(n = 0, 2-5).
