The effect of a magnetic field (6 kG) on the delayed fluorescence in a 1,4-Dibromonaphtalene at 300 K and 20 K is analysed using a new approach of calculation of the triplet-triplet annihilation rate constant. The agreement of the best fit between experiment and theory allows reaching at 300 K and 20 K respectively the lifetimes and the interaction constant of the triplets pairs.
