What is the molecular formula of the alkane with 3 carbon atoms?
  but are present in the mass spectrum of the saturated hydrocarbons from oysters.’ Neither crude oil nor sedimental organic contaminants are probable sources of the mono-, di-, and tricyclo- alkanes which form the ions producing the latter peakings. Nevertheless, differences in the carbon numbers at which the ‘peakings’ maxima occur in the various columns of tables 4, 5, and 7 as well as the alternate high or low values of odd and even C ‘parent ions’ in table 5 may be more suggestive of …
