摘要：
The H-1 CW off-resonance decoupled C-13 NMR spectra of (E)- and (Z)-cycloalkenes (C5-C-12) were measured. The higher order C-13 NMR multiplets obtained for the unsaturated carbons allow the determination of the vicinal H-1,H-1 coupling constant between the vinylic protons and thus the assignment of the configuration of the -CH2CH=CHCH2- fragment.
