Natural abundance 17O and 13C NMR spectra for eleven diarylketenes are reported. 17O shifts show invariance with para substitution and a shielding due to ortho substitution. A buttressing effect is observed for bis(2,3,4,5,6‐pentamethylphenyl)ketene. A comparison between ketenes and isocyanates is made. The importance of cylindrical symmetry for half‐height linewidths is discussed.
