Abstract : The patent describes a process whereby tris (1,1,1,2,2,3,3-heptafluoro-7,7-dimethyl - 4,6 - octanedionate)europium(III) is added to a sample of a mixture of isomeric azoxybenzenes after which the sample is subjected to nuclear magnetic resonance. The spectrum obtained makes it possible to identify each isomer as well as to determine their relative amounts in the mixture.
