The decay of the organics was followed using a gas chromatograph with a flame ionization detector (GC-FID), and the rate constants were determined using a relative rate method with different references. Room temperature rate constants are found to be (in cm3 molecule-1 s-1): k1(OH + CF2ClC(O)OCH3) = (1.1
