• The mercury photosensitized reaction of propylene-<I>cis</I>-1-<I>d</I><SUB>1</SUB> and 1-butene-<I>cis</I>-1-<I>d</I><SUB>1</SUB> was studied by means of microwave spectroscopy combined with gas chromatography and mass spectrometry. At pressures above 100 mmHg <I>cis-trans</I> isomerization was the main reaction for both the propylene and 1-butene. The number of the absorbed quanta of photons and the number of molecules reacted was almost equal. However, at lower pressures, this condition was not satisfied. At pressures less than 30 mmHg, substantial amounts of the 2-<I>d</I><SUB>1</SUB> and 3-<I>d</I><SUB>1</SUB> propylene species were detected in the reaction mixtures. Decomposition of propylene into an allylic radical and a hydrogen atom with subsequent "recombination," was proposed to account for this observation. Similar results were obtained with 1-butene-<I>cis</I>-1-<I>d</I><SUB>1</SUB>.
