摘要：

Pulse radiolysis of cis-stilbene was carried out and transient absorption spectra were measured in varying concentrations in dichloromethane under air at room temperature. Concentration dependence of the spectral change indicates that cis-stilbene radical cations isomerize to trans-stilbene radical cations through interaction with a neutral cis-stilbene molecule, probably by way of a sigma-type dimeric radical cation.
