Origins of the differences in solvation by alkanes and perfluoroalkanes

Fluorescence and Phosphorescence from Higher Excited States of Organic Molecules

“…250 They reported also the excitation spectra of van der Waals complexes of xanthione with nine n-alkanes and six perfluoro-n-alkanes in a jet. 249 They showed that there are systematic microscopic solvent shifts of the S 2 origin bands depending on the number of carbon atoms in n-alkanes in the 1:1 complexes, although the shift is small for perfluoro-nalkanes. 249 Excited-state dynamics have been investigated for arylthioketones in solution and in the vapor phase including in a jet.…”
