Acrylic acid (CH2=CHC(O)OH) and methacrylates (CH2=C(CH3)C(O)OR), where R is an alkyl group,  are widely used in the industry of polymers, paper coating, paint formulations , etc.  In addition they are produced naturally by marine algae and in the rumen fluid of sheep. The atmospheric fate of  unsaturated and oxygenated volatile organic compounds (VOCs) is mainly their reaction with OH radicals. As part of an ongoing program in our laboratory to study the atmospheric chemistry of oxygenated species, we report relative rate coefficients for the gas-phase reactions of OH radicals with acrylic acid (k1) and thr
