Abstract:	The title reactions have been studied at room temperature by applying the discharge flow method coupled with laser induced fluorescence detection of methoxy radicals and resonance fluorescence detection of bromine atoms. The following rate constants were determined: CH₃O + Br Õ products (1) k₁ (298 K) = (3.4 ± 0.4 (1)) × 10¹³ cm³ mol^-1 s^-1, CH₃O + Br₂ Õ products (2) k₂ (298 K) £ 5 × 10⁸ cm³ mol^-1 s^-1.

Keywords:	Radical-radical reactions Br atom CH3O radical
