h5 style="MARGIN: 0cm 0cm 0pt; LINE-HEIGHT: 200%">  Absolute rate coefficients have been determined for the gas-phase reactions of hydroxyl radicals with methyl acrylate (k1), methyl methacrylate (k2) and ethyl acrylate (k3). Experiments were performed using two different techniques, the relative rate method and the pulsed laser photolysis-laser induced fluorescence technique. The kinetic data obtained were used to derive the following Arrhenius expressions in the temperature range  253-374 K (in units of cm3 molecule-1 s-1):
