Abstract
cis-2-Butene has been photolysed at 8.44, 8.44–9.56, and 10.03 eV in the presence of SF6 and of several other additives. A major isomerization process is observed at 10.03 eV: Φ(trans-butene-2) [Formula: see text]. At 8.44 eV this yield is of the order of unity. A chain mechanism initiated by kinetically excited hydrogen atoms is proposed to explain the observed effects. Although we were unable either to identify the chain carrier with certainty or to eliminate the possibility of an ionic initiation at 10.03 eV, the chain carrier is a derivative of SF6, possibly the SF5 radical.
