Extract

Probe molecules P placed in dilute solution and absorbing radiation Ia produce electronically excited species P* which can return to thermal equilibrium by radiative (luminescence) kR and nonradiative (heat) kNR processes. The relative probabilities of the two decay channels are determined by measuring the lifetime τ of P* and the luminescence quantum yield φ = I/Ia, where I is the luminescent intensity. The kinetic scheme and relevant relations are
