The magnetic field effect (≤ 0.59 T) on the quintet–quintet fluorescence of m-phenylenebis(phenylmethylene) (MPBP) was studied in a rigid glass, decaline–cyclohexane (3 : 1) mixture, at 77K. The fluorescence decay rate of MPBP increases in a magnetic field. The effect on the MPBP fluorescence is explained in terms of the Zeeman mixing of excited quintet sublevels of MPBP.
