%X The 13C n.m.r. spectra of a number of ethyl (3-aryl)azo-, (4-aryl)azo-, 2-(4-arylethenyl)-cinnamates have been measured in CDCl3. Comparison of the data with those for the corresponding ethyl 3-arylpropenoates has been used to investigate the attenuation of electronic effects by the 3- and 4-azophenylene and the 4-ethenylphenylene linkages.
