Abstract. Recent studies in atmospheric chemistry have stimulated interest in the structures and properties of chlorine species and contributed to the discovery of new chlorine oxides with isomeric structures. Dichlorine oxides with oxidation states I, III, V and VII are associated with the corresponding oxoacids HClO, HClO2, HClO3 and HClO4, formally produced by their reactions with water. However, this scheme overlooks the various isomers of the chlorine oxides. A systematic nomenclature is proposed that identifies the structure of each compound and facilitates the identification of the oxoacid resulting from hydrolysis.
