Abstract
Rate constants for the reaction of hydroxyl radicals with dibromometha ne have been measured by discharge flow-resonance fluorescence techniq ue (DF-RF) over the temperature range 288-368 K. The derived Arrhenius equation is k(1) = (1.51+/-0.37) x 10(-12) exp(-(720+/-60)/T) cm(3) m olec.(-1) s(-1). The tropospheric lifetime of dibromomethane has been estimated to be 0.29 years. An ozone depletion potential (ODP) value o f 0.10 for dibromomethane has been obtained.
