What is triplet lifetime?

Triplet state lifetimes (τT) and quantum yields (ΦT) The extent to which a Pc as a photosensitizer is able to generate singlet oxygen is gauged by its triplet quantum yield and lifetime. The quantity of the absorbing molecules undergoing ISC to the triplet state is known as the triplet quantum yield.

What is triplet and singlet?

Singlet state: All electrons in the molecule are spin paired. It is called a singlet because there is only one possible orientation in space. Triplet state: One set of electron spins is unpaired. It is called a triplet because there are three possible orientations in space with respect to the axis.
