A note on the green dyadic calculation of the decay rates for admolecules at multiple planar interfaces

The Green dyadic formulation for calculating classical decay rates of admol ecules at multiple planar interfaces first published by Chance, Prock and S ilbey is reexamined. It is pointed out that, for the case of fluorescing mo lecules sandwiched between a system of super- and substrate interfaces, the original formalism requires significant modifications in order to lead to results consistent with those obtained from the Sommerfeld radiation theory .
