Abstract:

It is demonstrated that the results of the Zeeman effect on the observed phosphorescence spectrum at low temperatures can yield information concerning the mechanism of the singlet 1 to triplet 1 nonradiative process. The results of this as well as the Zeeman-PMDR technique support the direct singlet 1n,pi to triplet 1pi,pi intersystem crossing mechanism for quinoxaline in durene, in spite of the larger energy gap involved as compared with the singlet 1 to triplet 2 to triplet 1 mechanism.
