The quantum yield of triplet formation and triplet lifetime of pyridine in the liquid phase by the two-photon-excited time-resolved thermal lens method

The quantum yield of triplet formation and the triplet lifetime of pyridine are measured for the first time in the liquid phase using the two-photon-excited time-resolved thermal lens method. The triplet lifetime (1.0 μs) is very short and the quantum yield of the triplet formation (0.9) is large. T...

Description
Summary:The quantum yield of triplet formation and the triplet lifetime of pyridine are measured for the first time in the liquid phase using the two-photon-excited time-resolved thermal lens method. The triplet lifetime (1.0 μs) is very short and the quantum yield of the triplet formation (0.9) is large. These results are discussed in comparison with the same parameters reported for the gas phase.
