WAVELENGTH EFFECT ON THE PHOTOCHEMICAL REACTIONS OF (Z)-2,5-DIMETHYL-1,3,5-HEXATRIENE: SELECTIVE EXCITATION OF ROTAMERS

The UV absorption spectrum of Z-2,5-dimethyl-1,3,5-hexatriene 1 is typical of a cZt triene, but the long wavelength tail indicates the presence of the (minor) cZc rotamer.The sudden change in the photoreactivity of 1 around 290 nm is in agreement with selective excitation of these rotamers.No indication is obtained for an intrinsic excitation energy dependence of the photoreactivity of the individual rotamers.
