A low total pressure (10 torr) flowing gas system and a high total pressure (760 torr) CH/sub 3/ON-O-NO photolysis system are used to study the reaction of OH with isoprene. Both systems give methyl vinyl ketone, methacrolein, and 3-methylfuran as the major products; 1,2-addition is favored over 1,4-addition by a factor of 7. From the proposed mechanism and reaction pathways, it is concluded that more than 2 mol of NO will be oxidized to NO/sub 2/ for each mole of isoprene oxidized by OH. Direct reaction of isoprene with NO/sub 2/ was also measured.
