The rate coefficient of the gas-phase reaction of 4-terbutylcyclohexanone (4-TBCH) with Cl atoms was measured using two detection techniques. GC-FID using a Teflon collapsible chamber kCl = (2.84±0.64) ×10-10 cm3 molecule-1 s- 1 and ?in situ? FT-IR spectroscopy kCl = (2.77±0.56) ×10-10 cm3 molecule-1 s- 1 in a glass reactor at 298 K at 760 Torr. Additionally, the products were identified for the first time by SPME / GC-MS and atmospheric implications were assessed. Keywords: Gas-phase, Cyclic carbonyls, Kinetics,,Smog chambers .
