Some additional negative ion reactions of possible D-region importance have been measured in the ESSA flowing afterglow system at 300°K. It has been found that NO3- does not react with atomic oxygen or atomic nitrogen with a rate constant as large as 10-11 cm3/sec. The electron affinity of NO3 is found to be greater than that of NO2 by more than 0.9 eV. It is pointed out that conversion of O2- to O4- followed by subsequent reactions of the O4- may play an important role in D-region negative ion chemistry. Rate constants for the reaction of O4- with NO, CO2 and O are reported. The reaction of O4- with CO2 produces CO4-. Rate constants for the reactions of CO4- with NO and O are reported.
