Tunable laser I\*(zPI/2) quantum-yield measurements are presented for CH 2 I 2 in the wavelen,$h range 248-340 nm. The results suggest that a curve-crossing mechanism is operative in the dissociation\_

The quantum yields for production of I(2P3,2) and I\*('P& at 248 nm are reported for a variety of alkyl and substituted-alkyl iodides using the technique of two-photon atomic laser-induced fluorescence. These results are combined with those of others to provide quantum yields over a wide range of ra
Excited iodine atoms :(\*PI/~) are formed by laser irradiation of C2FS I at 2950 A. The mczm radiative lifetime T of these metastsble atoms and their bimolecular rate constant k2 for deactivation in collisions with C2 F5 I were measured to be: T = 108 +-10 ms; k2 = (1.8 i 0.1) X 10-l' cm3/molec s. \
