The transfer of electronic excitation energy from the lowest excited singlet and triplet states of a number of aromatic hydrocarbons and ketones to the lowest excited singlet and triplet state of biacetyl has been studied in hexane and benzene solution at room temperature by the spectrophotofluorometric method. Singlet-state lifetimes for benzene, toluene, diphenyl, and acetone are reported and triplet-state lifetimes for diphenyl, naphthalene, acetophenone, and acetone are also obtained. Useful information concerning the triplet states of other donors is also obtained by comparing the phosphorescence to fluorescence ratio of biacetyl when biacetyl alone is irradiated with the ratio obtained when a mixture of biacetyl and the donor is excited at wavelengths absorbed by the donor.
