Abstract
The quenching by benzene, 3-methylpentane, n-decane and n-hexadecane of the second excited singlet state of xanthione (τ(s2) = 160 ps) in inert, nonpolar perfluoro-1,3-dimethylcyclohexane has been studied using picosecond time-resolved fluorescence decay methods. This system is used to test the application of the Smoluchowski-Collins-Kimball (SCK) model for diffusion-limited, time-dependent quenching. The quenching mechanism is shown to involve short-range interactions, and SCK model provides a satisfactory theoretical basis for describing the process.
