摘要: Rate coefficients for the IO self-reaction, + → products (4), were determined over range 250−320 K and found to be independent of temperature with an average value (9.9 ± 1.5) × 10-11 cm3 molecule-1 s-1. Absorption cross sections radical measured between 340 480 nm. The absorption section at peak (4,0) band was as a function temperature. is essentially 373 203 (3.6 0.5) 10-17 cm2 molecule-1. Comparison previous measurements discussion atmospheric implications these results are also presented.
