摘要：

At certain magnetic fields, when the energy separations between the τx - τy spin levels and between the τy - τz levels of triplet coumarin become equal, intensity changes are observed in the phosphorescence of coumarin doped in a single crystal of durence cooled to 1.6 K that can be attributed to cross relaxation (CR) between the τx - τy spin levels of one triplet coumarin molecule and the τy - τz spin levels of another triplet coumarin. Rate equations that describe the time behavior of the populations of the spin levels which are involved in the CR process are described and numerically solved. CR behavior is found to be strongly dependent on the total coumarin triplet concentration. © 1979.
