AbstractDirect and long‐range 13C1H coupling constants are presented for the enone moieties of cyclopent‐2‐enone, cyclohex‐2‐enone and their protonated derivatives. A correlation is given between the experimental values and the results of quantum chemical calculations (CNDO/2, INDO). The existing calculations are modified in order to improve the relationship between the calculated and experimental results.
