Singlet Oxygen and Iodine Monofluoride Collisional Energy Transfer Mechanism

Abstract

The reaction between singlet oxygen (O2(a) and O2(b)) and iodine monofluoride (IF) occuring in a flowing reactor was observed as a means to study the energy transfer mechanism between these two molecules. Several researchers have demonstrated that singlet oxygen will efficiently pump IF(X) to the IF(B) state, however the exact mechanism has not been determined. The purpose of this research was twofold. First is to identify IF(B) emission due to pumping by O2(b) emission intensity as a function of the concentration of the individual reactants. The IF(B) emission spectrum indicates that O2(b) pumping of IF(X) to the IF(A') state cannot be discounted. Quenching coefficients for IF precursors are presented and compared to literature values.
