at 296 ± 2 K and 740 Torr total pressure of synthetic air, for the gas-phase reaction of OH radicals with the dibasic esters dimethyl succinate [CH3OC(O)CH2CH2C(O)OCH3], dimethyl glutarate [CH3OC(O)CH2CH2CH2C(O)OCH3], and dimethyl adipate [CH3OC(O)CH2CH2CH2CH2C(O)OCH3]. The rate coefficients obtained were (in units of cm3 molecule−1 s−1): dimethyl succinate (1.89 ± 0.26) × 10−12; dimethyl glutarate
