The photolysis of ethylene was carried out at room temperature at 1634 Å and 1849 Å. Products at both wavelengths were hydrogen, acetylene, ethane, n-butane and 1-butene. Product analysis and the radical scavenger technique indicate the primary processes to be as follows.
(Remark: Graphics omitted.)
The molecular elimination process in the primary processes varied with wavelengths, and was determined to be 47% and 53% at 1634 Å and 1849 Å, respectively. With reference to the percentage reported at other wavelengths, it is pointed out that molecular elimination is suppressed with the increase in excitation energy.
