The rate coefficients for the reaction OH + CH3CH 2CH2OH → products (k1)and OH + CH 3CH(OH)CH3 → products (k2) were measured by the pulsed-laser photolysis-laser- induced fluorescence technique between 237 and 376 K. Arrhenius expressions for k1 and k2 are as follows: k1 = (6.2 ± 0.8) × 10-12 exp[-(10 ± 30)/T ]cm3 molecule-1 s-1, with k1 (298 K) = (5.90 ± 0.56) × 10-12 cm3 molecule-1 s-1,and k2 = (3.2 ± 0.3) × 10-12 exp[(150 ± 20)/T ]cm3 molecule-1 s-1, with k2 (298) = (5.22 ± 0.46) × 10-12 cm3 molecule-1 s-1. The quoted uncertainties are at the 95% confidence level and include estimated systematic errors. The results are compared with those from previous measurements and rate coefficient expressions for atmospheric modeling are recommended. The absorption cross sections for n-propanol and iso-propanol at 184.9 nm were measured to be (8.89 ± 0.44) × 10-19 and (1.90 ± 0.10) × 10-18 cm2 molecule-1, respectively. The atmospheric implications of the degradation of n-propanol and iso-propanol are discussed. © 2009 Wiley Periodicals, Inc.
