Notes:
The products of the reactions of HCl or HBr with nitrogen dioxide at 12 K have been examined using Raman spectroscopy. For the NO2+HCl reaction spectroscopic evidence for Cl3+, asym-N2O2, N2O3, N2O4, ClNO2, ClNO3, NO3-, NO2-, and sym-N2O2 was found. For the reaction with HBr only Br3+, was detected due to resonance Raman enhancement effects. These results are consistent with the previously proposed gas-phase reaction scheme for HCl+NO2. However, the reaction proceeds further at low temperatures to produce Cl3+ (or Br3+). The Raman frequencies for Cl3+ were observed at 515(ν3), 462(ν1), and 236 cm-1(ν2). The Br3+ resonance Raman spectra, which represent the first well documented spectra for this species, show strong fundamental bands at 281(ν1) and 227 and 238 cm-1 (doublet for ν2) as well as an overtone doublet at 471 and 487 cm-1.
