@[email protected] of an excited molecular entity in the absence of radiationless transitions. The reciprocal of the first-order @[email protected] for the radiative step, or the reciprocal of the sum of these rate constants if there is more than one such step. The equivalent term, natural lifetime, is discouraged.
Notes:
- Approximate expressions exist relating \(\tau_{0}\) to the @[email protected] of the emitting transition.
- The subscript \(0\) is used in this definition, whereas the superscript \(0\) is used to indicate a non-quenched @[email protected] in the Stern-Volmer kinetic relationships.
