Studies of Chemiluminescence in Boron Atom Reactions with O2, SO2, N2O, NO2 and H2O2

摘要

Chemiluminescence has been observed in the single collision reactions of boron atoms with O2, SO2, N2O, NO2, and H2O2. Experiments were performed in a beam-gas apparatus using photon counting to detect the optical signals. The electronically excited ((A sup 2) Pi) state of BO was observed in all reactions. In addition, the BO2((A sup 2) Pi mu) state was observed in the reaction of boron with SO2. Cross sections for the production of electronically excited molecules were determined. In the reactions of boron with SO2, the branching ratio was obtained for the two observed chemiluminescent reaction channels. The vibrational distributions in the electronically excited state of BO were determined in the reactions where the spectra were adequately resolved. Some implications of the results are discussed.
