elative rate coefficients of the reactions of O3 with (Z) - and (E) - 3-hexen-1-ol and (E)-2-hexen-1-ol have been determined in an environmental chamber with in situ FTIR detection of the reactants at 298 K and 760 Torr. The following rate coefficients (in units of 10-17 cm3 molecule-1 s-1) have been determined: (6.04 ± 0.95) for (Z)-CH2(OH)CH2CH=CHCH2CH3; (5.83 ± 0.86) for (E)-CH2(OH)CH2CH=CHCH2CH3; (5.98 ± 0.73) for (E)-CH2(OH)CH=CH(CH2)2CH3. This is the first kinetic study for the reactions of O3 with (E)-2-hexen-1-ol and (E)-3-hexen-1-ol. Reactivity trends are developed and the atmospheric persistence of these compounds is calculated based on the rate coefficients.
