Abstract
On direct as well as benzil-sensitized irradiation in degassed benzene N-methoxy-1-(2-anthryl)ethanimine (I), ArC(CH3)=N-OCH3 (Ar: 2-anthryl ), underwent one-way Z-->E isomerization through a quantum chain proce ss. The barrier to Z-->E isomerization of I in the excited triplet sta te was determined by directly observing the change of T-T absorption s pectra from the Z triplet to the E triplet. Based on these results the potential energy surface of photoisomerization of I is discussed.
