Principal components analysis was applied to the 13C and 15N chemical shift data on a series of fifteen 1-(para-substituted-phenyl)-3-acetyl-3-methyltriazenes.It was found that the halogen-substituted triazenes formed a class, based on substituent effects, which was different from the remaining eleven triazenes.A one-component model described the halogen class, whereas a two-component model was necessary for a description of the second class.In the second class, substituent tended to cluster to form groups depending on their electronic character.
