โœฆ Synopsis

The magnetosensitivity time for the pyrene excimer delayed fluorescence of the exciplex system pyrene-N,Ndiethylaniline in methanol was studied by pulsed magnetic field techniques. The half-life of the magnetic effect was shown to be about 40 ns. The maximum magnetosensitivity time after photoexcitation appeared to be greater than 70 ns. The values are interpreted as geminate-pair lifetimes.
