The luminescence behavior of dilute solutions of benzene in cyclohexane is investigated for proton and ultraviolet excitation. Benzene fluorescence from proton excitation does not show the delayed component that has been reported for numerous aromatic solvents. Instead there is an initial rapid decay attributed to dynamic quenching followed by a slower decay approaching that observed for ultraviolet excitation. The initial quenching is shown to be consistent with intratrack quenching by transient species.
