    Don't know if there are any hardcore physical chemists here, but if there are, maybe they can answer this question for me:

    The formula for Forster energy transfer is k = (K^2 * J * 8.8E-28 )/(n^4 * tau_0 * r^6). J is the spectral overlap between donor emission and acceptor absorption, and tau_0 is the radiative lifetime of the donor. But what if the donor is nonemissive? Then both J and tau_0 are 0, and the equation turns into k = 0/0. How do I turn this into something meaningful?
