โœฆ Synopsis

The fluorescence lifetime of the SI electronic level of xanthione has been measured under supersonic jet conditions to be 345 I! 10 ps. Fluorescence lifetimes ranging from 240 to 370 ps were also measured, following excitation into different SL vibrational levels. This confirms that, in addition to a well known solvent and internal C-H mode dependence, the non-radiative coupling of Sj to lower electronic states is also a function of the vibrational mode excited.

Time-correlated single-photon counting experiments at 2 25 ps resolution have been used to measure the S, fluorescence decay time of xanthione in different fluid solvents. Systematic differences in Sz lifetime in the range 20-30 ps are revealed for a homologous series of n-alkane solvents, and an in
