Abstract

The reaction of singlet atomic oxygen with CH3Br, CH2Br2, CHBr3 and CDBr3 trapped in argon matrices at 15 K have been studied by FTIR and by UV spectroscopy. CHBr3 and O(1D) reacts in the matrix to form COBr2 and HBr or HCOBr and Br2. The reaction between O(1D) and CH2Br2 in the matrix appears to lead directly to a HBr(DOT)(DOT)HBr(DOT)(DOT)CO complex while in the reaction between CH3Br and O(1D) the major product seems to be a quite photostable complex between H2CO and HBr.
