Recombination of iodmc atoms gcncrdtcd by shock heating I2 in
Ar is studied in an unsteady cxpanslon. The thrccbody recombination rate cocfficirnt has been mcasurcd as 3 X 1O*5 (T/298)-1-56 cm6 IIUJI-~ s-l bctwccn 500 and 1450 K. Coupling of v~br.it~on~l iiild chcmiwl rclJxation is found to occur in the exp.msion.

The Iewmbination of iodine atoms in the presence of NO has been studied by laser flash photolysis in the inert gas He, at pressures between 1 and 200 atm and at temperatures from 320-440 K.
