Inokuti-Hirayama equation

Mataga et al. (18) studied energy transfer from the excited triplet of benzophenone to naphthalene by laser flash photolysis at 77K and showed that the non-exponential decay curves of the benzophenone triplet obey the Inokuti-Hirayama equation (eq (ID). Inokuti and Hirayama (17) themselves compared the data on triplet-triplet transfer between certain aromatic molecules obtained by Terenin and Ermolaev with eq (11) and reported that a good fit was found with an appropriate choice of the parameters C and 7. 

In the case of an electric dipole-dipole interaction, the decay of the emission intensity is described by the Inokuti-Hirayama equation (Inokuti and Hirayama 1965) ... 

In the following paragraphs, this self-quenching is treated qualitatively. Dexter s theory of energy transfer by the exchange mechanism can probably be fit to the data. The proper equations have been developed by Inokuti and Hirayama. In order to treat the data properly, the Ro value for the If/N interactions should be determined from model studies. This we have not yet done.
