28. 3MLCT states are in rapid equilibrium, the emission intensity decays with single-exponential kinetics, and the lifetime is a Boltzmann-weighted average of the lifetimes of the different states. Therefore, as the temperature is decreased and the distribution shifts to lower energy, the excited-state lifetime increases.

31. There is some justification for this approximation based on earlier work (ref 32) showing that the nonradiative rate constant is relatively temperature independent.
