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(More)
The Raman spectrum of all-trans anhydrovitamin A in hexane at 77 degrees K is presented. The similarity of the Raman spectra of anhydrovitamin A and the protonated Schiff base of retinal is striking. The implications of this for visual pigment studies and bacteriorhodopsin are discussed. Tentative assignments of geometry for four cis-trans isomers of(More)
