• The mass spectra of 1-alkenes ranging from C<SUB>5</SUB> to C<SUB>10</SUB> were measured at temperatures of the ion source 120–250 °C. Fragmentation M<SUP>+</SUP>\overset<I>m</I><SUB>28</SUB>→(M–28)<SUP>+</SUP> and M<SUP>+</SUP>\overset<I>m</I><SUB>28</SUB>→(M–29)<SUP>+</SUP>, where <I>m</I><SUB>28</SUB> and <I>m</I><SUB>29</SUB> denote the metastable peaks of the fragmentations, were studied. The behavior of the curve of the intensity ratios <I>R</I>′<SUB>28</SUB>=<I>m</I><SUB>28</SUB>⁄<I>F</I><SUB>28</SUB> and <I>R</I>′<SUB>29</SUB>=<I>m</I><SUB>29</SUB>⁄<I>F</I><SUB>29</SUB>(<I>F</I><SUB>28</SUB> and <I>F</I><SUB>29</SUB> denote the intensities of the (M–28)<SUP>+</SUP> ion and the (M–29)<SUP>+</SUP> ions, respectively), <I>versus</I> temperature <I>T</I> of the ion source of the mass spectrometer is explained by the quasi-equilibrium theory (QET).
