✦ Synopsis

Photoexcited 1,4dewarnaphthalene (1) rearranges in high efficiency to excited naphtbdene in both the singlet and the . triplet manifold. Assuming the relative efficiencies of fluorescence to intersystem crossing of 1 are similv to those of substituted benzenes, the rearrangement of triplet 1 to triplet naphthalene may be adiabatic. The relative efficiencies of fluerescence to rearrangement to singtet excited naphtbtrlene from singlet excited 1 at 77 # depends on the wavelength of exciting light, the shorter the wavelength, the more efficient the rearrangement.
