dc.description.abstractThe formation of $O_{2}$ ($^{1}\Sigma^{+}_{g}$) through sensitization by the triplet state of certain aromatic molecules has been previously demonstrated. The higher energy state of $O_{2}(^{1}\Sigma^{+}_{g})$, however, has not been previously observed in sensitization. Using a time-resolved flash photolytic technique we have been able to demonstrate through its emission at 7620\AA the formation of $O_{2}(^{1}\Sigma_{g}^{+})$ by energy transfer from the triplet states of several aromatic molecules including 1-fluoronaphthalene perfluoronapthalene, naphthalene, phenanthene, benzene, and benzaldehyde. We have also demonstrated that excited $SO_{2}$ sensitizes the formation of $O_{2}(^{1}\Sigma_{g}^{+})$ but the evidence points to the sensitizing state as a vibrationally excited singlet state, most likely $SO_{2}(^{1}{B}_{1})$, according to the reaction $SO_{2}(^{1}{B}_{1})^{v}+{O}_{2}(^{2}\Sigma_{g}^{-})-SO_{2}(^{3}{B}_{1})+O_{2}(^{1}\Sigma_{g}^{+})$.en_US
