Abstract

^1^H, ^13^C and ^17^O NMR spectra of fenchone and six monochlorofenchones have been recorded. The second‐order ^1^H NMR spectra were analysed by an iterative computer program. The ^1^H and ^13^C chlorine‐induced substituent chemical shifts (SCS) were calculated. The vicinal coupling constants proved to be essential in the assignment of the chemical shifts of the geminal methyls. No clear correlation was observed between the chemical shifts of the carbonyl oxygen and the carbonyl carbon. All monochlorofenchones were previously unknown compounds and were synthesized for this work.
