Helleis, F., Crowley, J. and Moortgat, G. (1994). Temperature dependent CH₃OCl formation in the reaction between CH₃O₂ and ClO. Geophysical Research Letters 21: doi: 10.1029/94GL01280. issn: 0094-8276.

The reaction CH3O2+ClO→CH3OCl+O2 (2b) has been investigated at temperatures of 295, 255, 230 and 215 K. The temperature dependent branching ratio for CH3OCl formation (&agr;2b) is given by &agr;2b=(T/300)-1.65 -0.223exp(411/T). The result at 200 K (ca0.23) can be combined with our previous determination of the overall rate constant for the reaction between CH3+ClO [Helleis et al, 1993> to calculate a channel specific rate constant for reaction 2b of ca (4.1¿1)¿10-13 cm3 molecule-1 s-1 at the temperatures prevalent in the lower polar stratosphere at springtime. ¿ American Geophysical Union 1994
