Hydroxyl (OH) is the key reactive chemical specie that controls the oxidative capacity of thetroposphere. The OH radical-initiated oxidation reactions determine the atmospheric lifetimeand concentrations of most trace gases in the troposphere, e.g. NOx [1].The hydroxymethyl radical (CH2OH) has attracted considerable research interest due topractical and scientific considerations [2]. It is involved in pyrolytic and oxidative paths ofmethanol combustion and may also participate in reactions that affect the atmosphere.
