Abstract
Long‐range radiationless energy transfer from the triplet states of aromatic hydrocarbons to the singlet states of fluorescent dyes (10—3 M) is used to measure the efficiencies of energy dissipation (φF, φIS, φP) for triphenylene, phenanthrene, p‐terphenyl, chrysene, naphthalene, and/or their deuterated counterparts. Rhodamine B, rhodamine 6G, acriflavin, and fluorescein were found to be suitable acceptors. By measuring phosphorescence efficiencies directly, reliable estimates of T→S radiative rate constants can be obtained.Keywords
