Abstract
The photochemistry of the E, E-and E, Z-geometric isomers of 1, 2-bis (ethylidene)- cyclopentane and-cyclobutane, and 2, 3-bis (ethylidene) norbornane has been studied in hydrocarbon solution at room temperature; the results are inconsistent with the classical theoretical models for diene cis⇌ trans photoisomerization and ring closure, which assume that both processes involve only simple torsional motions about (one or both of) the ...
