This paper describes the result obtained on the decomposition of paraffins and olefins by electron impact. Appearance potentials of three paraffins and four olefins are determined with a Hitachi Mass Spectrometer Type RMS-3. Bond energies between atoms in some paraffins and olefins are deduced from the appearance potentials of ion fragments. Mass spectra have also been taken over a wide range of ionization voltage. The variation of the amount of ion fragment with the increase of ionization voltage can be divided into three types.
