Abstract:

Using a drift tube mass spectrometer coupled with a laser photon source absolute photodestruction cross sections as a function of photon energy have been measured for various room temperature 300 K atmospheric ions. These ions are O2-, O3-, O4-, NO2-, SO2-, O2-H2O, CO4-, SO4-, O2O2, O2H2O, O2CO2, O2SO2, CO2CO2, and HH2O sub n 1 to 4. Author
