Evidence for adduct formation between ONOO- and CO2 from high-pressure pulse radiolysis
The activation volume for the reaction of CO2 with ONOO- has been determined to be -22 cm(3) mol(-1) using the high-pressure pulse radiolysis technique. The significant negative volume of activation provides conclusive evidence for a short-lived cyclo-adduct formation between ONOO- and CO2.
