New compound class found in atmosphere

The existence of the hydrotrioxides in the atmosphere was, until now, only speculation.

Laboratory set-up of the free-jet flow experiment at TROPOS in Leipzig, with that direct evidence was provided for the first time that the formation of hydrotrioxides (ROOOH) also takes place under atmospheric conditions from the reaction of peroxy radicals (RO2) with hydroxyl radicals (OH).
