  1. aPeak wavelengths of absorption and fluorescence spectra in toluene.
  2. bFull-widths at half-maxima.
  3. cLowest excited singlet (S1) and triplet (T1) energy levels are determined from the peak values of fluorescence and phosphorescence spectra, respectively, in dilute toluene at 77 K.
  4. dΔES1T1 = S1 – T1.
