The time-resolved thermal lens technique is used to measure quantum yields of triplet formation and triplet lifetime in the solid phase at low temperature. The time dependence of the thermal lens signal of pyridazine in the solid phase is very different from that in a fluid medium. These results are
The quantum yield of triplet formation (a,,,) and the triplet lifetime of pyridazine in the liquid phase at room temperature and measured by the transient grating method. Relatively small 4jiW and a very short triplet lifetime compared with those in the solid phase at low temperature are obtained. T
