Smog chamber/FTIR techniques were used to study the chlorine atom initiated oxidation of CF3CH2CF2CH3 in 700 Torr of N-2/O-2 at 296 K. Relative rate techniques were used to measure k(CI + CF3CH2CF2CH3) = (1.02 +/- 0.14) x 10 (15) cm(3) molecule (1) s (1). The reaction proceeds via attack on the - CH3 group leading to formation of CF3CH2CF2CHO which in turn is oxidized to CF3CHO and COF2. The integrated IR band strength of CF3CH2CF2CH3 over the range 600 - 1600 cm 1 is (1.89 +/- 0.10) x 10 (16) cm(2) molecule (1) cm (1). The global warming potential of CF3CH2CF2CH3 is estimated to be 997 over a 100 year time horizon. (c) 2008 Elsevier B. V. All rights reserved.
