Energy transfer in organic systems. VIII. Quenching of naphthalene fluorescence by biacetyl

This is the authors' abstract. We don't add key points for this paper.

For Pt. VII see abstr. A5178 of 1969. The rate parameters of naphthalene fluorescence quenching by biacetyl in ten solvents of viscosity eta =0.34 to 172 cP have been determined from relative fluorescence yield and lifetime measurements. The data are consistent with electron-exchange interaction quenching with a range of 11 AA, and with diffusion coefficients given by the Stokes-Einstein relation, except for liquid paraffin.
