he relative rate technique was used to determine the rate coefficients of the reactions of OH radicals with (Z)-2-hexen-1-ol (k1), and (E)-3-hexen-1-ol (k2), at (296 2) K and (750 10) Torr of N2 or pure air.The reactions were investigated using a 200 L Teflon reaction chamber and a gas chromatograph coupled with flame-ionization detection. The rate coefficients were derived. This is the first experimental determination of k(1) and k(2). A comparison between the experimental rate coefficients (k) and the calculated rate coefficients using the structure reactivity relationship (SAR) method (kSARexp), for the reaction of different unsaturatedalcohols with OH radicals is presented. The atmospheric lifetimes of the studied alcohols were estimated considering the rate coefficients of their reactions with OH and NOradicals. The radiative efficiencies (REs) were obtained from the infrared spect
