Abstract
The photolyses of
cis-
and
trans
-hexa-1, 3, 5-triene at wavelengths of 228.8 and 253.7 nm and of cyclohexa-1, 3-diene at 265.4 and 280.4 nm have been studied in the gas phase at various pressures and in the presence of added gases. At low pressures, the limiting quantum yield for hexatriene photolysis is unity within experimental error, and it is shown that the pressure dependence of all the observed interconversions of C

isomers and of benzene formation can be explained by reactions of vibrationally excited molecules produced by very rapid internal conversion.
