Summary
The results of a crossed molecular beam study of the chemiluminescent reaction NO + 0/sub 3/ ..-->.. NO/sub 2/ + 0/sub 2/ are discussed. The chemiluminescence as a function of collision energy and an excitation function were obtained using a translationally cooled supersonic NO beam. An investigation into the role of the internal energy states using an effusive NO beam and a supersonic O/sub 3/ beam has been presented. The results show that chemiluminescence enhancement occurs when high and low temperature NO experiments are compared. The role that other energy modes may have is discussed. The observed enhancement is consistent with the concept that the chemiluminescence cross section increases with NO molecular rotation for low J states. The second part discusses the role of NO/sub 2/ in preserving a global ozone balance. NO/sub 2/ vertical profiles based on Noxon's (1979) column measurements were derived. The method of instantaneous rates was used to calculate the rate of ozone production and destruction by O/sub x/ and NO/sub x/ on a grid that covered the entire globe. The results were presented as a function of altitude and latitude in contour plots.
