Abstract The recombination of iodine atoms following the flash photolysis of iodine in the presence of nitric oxide is interpreted through the mechanismwith k 1 = 3.5 × 10 9 l. 2 /mol 2 ·sec; k 2 ≈ 1 × 10 11 l./mol·sec; k 3 = 2.1 × 10 7 l./mol·sec at 298°K; E 3 = 11 kJ/ mol; and ΔH° 1 = 76 ± 6 kJ/mol. Lower and upper limits for the equilibrium constant are also established. The absorption spectrum of INO has been extended down to 223 nm and extinction coefficients for the region of 223–310 nm and 360–460 nm have been measured.
