The absorption of 160-nm light by cyclohexane in mixtures of cyclohexane, benzene, and tetraphenylmethylenediamine results in an emission spectrum consisting of the simultaneous fluorescence from all three components. A mechanism for the development of this spectrum and its dependence on benzene concentration is constructed and shown to be quantitatively consistent with the results of independent measurements on the separate components. In the absence of tetraphenylmethylenediamine, the quenching of cyclohexane fluorescence by benzene is found to be well represented by the standard diffusion model but with important contributions from transient terms. However, the concomitant sensitization of benzene fluorescence via energy transfer from cyclohexane is found to occur with an efficiency factor of only 0.26 {plus minus} 0.02 per encounter.
