On the basis of Förster kinetics concerning long‐range energy transfer caused by dipole‐dipole interaction the √t ‐deactivation‐law has been derived under the assumption of a homogeneous spatial acceptor distribution (at the end of the forties). Recently, in particular ultra‐short time fluorescence and absorption measurements have shown that on the one hand this law holds in a wide range of physical conditions, but that under other circumstances the experimental results strongly deviate from the √t ‐law. In the present paper it is shown that a unified treatment of inhomogeneous distributions and indirect donor‐donor interaction via the acceptors can qualitatively, and in certain cases also quantitatively, remove the discrepancies mentioned. The analysis yields new parameters of dynamical processes.
