Abstract
| - Several reaction pathways on the potential energy surface (PES) for the reaction of CH3O2 radicals with Bratoms are examined using both ab initio and density functional methods. Analysis of the PES suggests thepresence of the stable intermediates CH3OOBr and CH3OBrO. CH3OOBr is calculated to be more stable thanCH3OBrO by 9.7 kcal mol-1 with a significant barrier preventing formation of CH3OBrO via isomerizationof CH3OOBr. The relative importance of bi- and termolecular product channels resulting from the initiallyformed CH3OOBr adduct are assessed based on calculated barriers to the formation of CH2OO + HBr, CH3O+ BrO, CH3Br + O2, and CH2O + HOBr.
