β¦ Synopsis
Laser induced fluorescence has been observed from the 0 3rT(O:) state of chlorine. Lifetimes have hem 19 to 208 Pa, but the radiative lifetime is too long te, bc extracted from the data. A rate mcMcbpnt of 3.2 x cm3 mol -' s'-' was measured for quenching by Cl1 or Ar, the removal process being collision indoced ~~~~~r~~ of the 3n(O$ state.

Long-chain chlorine-photosensitized oxidation has been observed in the gas phase at about 355'K for 1,1,2,2-and 1,1,1,2-C~H~C14, CZHClS, and CzC14 but not for CzHe, 1,2-CzH4C12, I,l,I-C2H3C13, CzH4, and 1,2-CzHzCIz. This is shown to depend on the exothermicity of the dissociation of the chloroethoxy
