Abstract
Chemiluminescence has been observed in the single collision reaction of boron atoms with O2, SO2, N2O, NO2, and H2O2. The experiments were performed in a beam‐gas apparatus using photon counting to detect the optical signals. The electronically excited A 2π state of BO was observed in all the reactions. In addition, the BO2(A 2πu) state was observed in the reaction of boron with SO2. Cross sections for the production of electronically excited molecules were determined. These cross sections for the reactions with O2, SO2, N2O, NO2, and H2O2 are, respectively, 0.048, 0.0078, 0.01, 0.023, and 0.005 Å2. 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.Keywords
