The rate enhancement would
increase the competition between the loss processes (e.g. RO2
removal by HO2/RO2 versus RO2 removal by NO). The loss of RO2 by
NO is very important in atmospheric chemistry because of direct
formation of organic nitrates (RONO2) or the production of O3
(through photolysis of NO2 and further reaction of the formed Oatoms
with O2) in the troposphere. Because of the smaller binding
energy, the participation of CH3O2.H2O complex in the peroxy selfreaction
is not favoured (English et al., 2008). However, the RO2
