✦ Synopsis

Mass spectra of mono-n-alkyl substituted acetylenes of type 1 containing at least 7 carbon atoms in the alkyl group, R , are characterized by key fragments of mass 82 and 96 which decompose by loss of a methyl radical. Spectra of di-n-alkyl substituted acetylenes of type 2 show these key fragments shifted by an appropriate mass number. These ions suffer further decomposition by loss of a C,H,, particle of mass 70. In addition key fragments of mass 67, 81, 82 and 95, 96 are again observed.
