Abstract
Photoisomerization of the linear polyene 1,3,5,7-octatetraene has been observed in an n-hexane matrix maintained at the boiling point of helium. To a good approximation, only the trans,trans and cis,trans isomers participate in the photochemistry. These compounds have been unambiguously identified by comparing the observed high-resolution fluorescence spectra to those of chromatographically purified reference compounds. Although the quantum yield of this process is probably low, its microscopic rate seems to compete favorably with vibrational deactivation.
