- 中文摘要: Proton magnetic resonance spectrum of thujic acid was studid at 60MC. Ethylenic proton spectra appeared in the range of 2.35T-4.89T. These are of interest form the point of view of structure determination. The proton spin-spin coupling constants were determined to be 10.0 cps for double-bonded vicinal protons, and 6.8 cps for single-bonded vicinal protons. Two barely resolved quartets suggest the spin-spin coupling between H1 and H0 for which the value was found to be 1.2 cps.
