• The decomposition of the (M–18)<SUP>\underset.+</SUP> ion of aliphatic alcohols and that of the M<SUP>\underset.+</SUP> ion of 1-alkenes are studied. The temperature effect of the ion source of a mass spectrometer on the ratios of the intensities of these ions, those of the ions produced from them by C<SUB>2</SUB>H<SUB>4</SUB> elimination, and those of the metastable ions for the corresponding fragmentation was measured and was compared with the results to be expected from a simple QET consideration. A discrepancy between the result expected and the experimental result was found for 1-alkenes. In order to clarify the cause of the discrepancy, the photoelectron spectrum was measured for 1-hexanol and for 1-hexene and was assumed to represent the internal energy distribution function, <I>P</I>(<I>E</I>), for each of these substances. Taking the shape of the <I>P</I>(<I>E</I>) into account, the result for 1-alkenes was explained.
