摘要：

The H-1 CW off-resonance decoupled C-13 NMR spectra of pheromones and unsaturated fatty acids were measured for the determination of the configuration of double bonds of the type -CH2-CH = CH-CH2-. The decoupling frequency corresponded to the resonance frequency of the CH2 protons. The 2nd order splittings in the observed multiplets of the olefinic carbon atoms allow an approximate determination of the vicinal coupling constant between the olefinic protons, and the configurational assignment of the double bond.
