Laser flash photolysis (at 248 or 308 nm) or aryl iodides in water or water/methanol solutions produces iodine atoms and phenyl radicals. Iodine atoms react rapidly with added I-to form 12-but do not react rapidly with 0 2 ( k I lo7 L mol-l s-l). Iodine atoms oxidize phenols to phenoxyl radicals, wi
A value of (6 f 1 j X 1O-34 cm6 molecule-2 s-' has been obtained for the room tcmperoture rate constant of the homogeneous recombination of fluorine atoms with He as the third body. ## Recently Ganguli and Kaufman [ 1) determined the recombination rate of F atoms using a Cl;! titration tcchniquz.
