Preferred Label : radiative lifetime;
Detailed label : radiative lifetime, τ0;
IUPAC definition : Lifetime of an excited molecular entity in the absence of radiationless transitions.
The reciprocal of the first-order rate constant 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.;
Scope note : the subscript 0 is used in this definition, whereas the superscript0 is used to indicate
a non-quenched lifetime in the stern-volmer kinetic relationships.; approximate expressions exist relatingt 0 to the oscillator strength of the emitting
transition.;
