An analysis of the mass spectra of ortho, meta and para isomers of monoalkylanisoles and monoalkylphenols, the alkyls being n ‐amyl, n ‐octyl and n ‐undecyl, has been performed. The regularities found allow determination of the structure of such compounds by inspection of the mass spectrum only. It was shown that Hammett's equation may be used for evaluating a ration of intensities of peaks originating formally from the simple β‐cleavage and that accompanied by hydrogen migration of the resulting fragment ions.
