Abstract
Thetrans-isomer of 1,2-di(2-naphthyl)ethylene is formed along with thecis-isomer in the one-quantum process under irradiation at the wavelength corresponding to the long-wave absorption band of 4a,4b-dihydrodibenzphenanthrene. The quantum yields of the photoinitiated processes were measured. The adiabatic mechanism was suggested for the photoinitiated ring opening in 4a, 4b-dihydrodibenzphenanthrene.
