The proton coupled 13 C NMR spectrum of propene has been analysed at 100.6 and 25.2 MHz and a complete set of C,H coupling constants is reported. In particular, vicinal and one‐bond coupling constants are discussed with respect to substituent effects of alkyl groups. An incremental method allows us to predict 1 J (CH) in more highly methyl‐substituted alkenes.
