Popis: The 13C NMR spectra of a wide range of monomeric para-substituted nitrosobenzenes have been determined and the results related to a wide range of published data for other para-disubstituted benzenes. It is shown that the nitroso substituent exercises a different pattern of effect for the 13C chemical shifts at the ipso C atom from at least twenty eight other substituents. It is noted that when the para substituent is a π-donor, the nitroso group functions in a different manner from that operative when the para substituent is a π-acceptor, a general possibility that has already been suggested in the recent literature.
