β¦ Synopsis
The technique of laser photolysis of alkyl and perfluoroalkyl iodides at 266 nm followed by time-resolved detection of the 1.3-pm emission from I*('PLI2) has been used to measure the rate constants for deactivation of I* by CH31, C'HJ, CF31, and CH,. The recommended values are (2.76 2 0.22) x
(2.85 2 0.40) x (3.5 2 0.5) x and (7.52 2 0.12) X lo-',, respectively, in units of cm3 molecule-' s -' .

The rate of the reaction CH212 + H I 2 CH,I + I , has been followed spectrophotometrically from 201 .O to 31 1 .Z0. The rate constant for the reaction I + CH,I, CH,I + I, fits the equation, log (k,/M-'sec-') = 11.45 f 0.18 -(15.11 f 0.44)/0. This value, combined with the assumption that E2 = 0 & 1 k
