摘要：
The external magnetic field effect as well as laser flash photolysis was employed to estimate die contribution of ion radical pairs to isomerization of trans-2-(3,3-dimethyl-1-butenyl)naphthalene (t-BN) in the presence of an electron acceptor in various solvents. The precursor of isomerization, t-BN triplet, was produced most efficiently almost through an exciplex in chloroform (epsilon=4.8) among the employed solvents.
