测定了21种甲基和卤代2-丙烯醇的~（13）C谱。的屏蔽数据进行了讨论，特别强调它们的3-卤代取代基的取向上的依赖。结果的线性回归分析给出了一组附加参数，这些参数将屏蔽与合理的精度（≤ 1 p. p.m.）相关联。 一组类似的参数已从已公布的数据生成的无环烯烃：这些参数集相互比较。最醇的质子谱的完整分析的结果也被提出。
The 13C spectra of 21 methyl- and halo-substituted 2-propenols have been determined. The shielding data are discussed with particular emphasis on their dependence on the orientation of the 3-halo substituents. Linear regression analyses of the results gave sets of additive parameters which correlate the shieldings with reasonable precision (≤ 1 p.p.m.). A similar set of parameters has been generated from the published data for acyclic alkenes: these parameter sets are intercompared. The results of complete analysis of the proton spectra of most of the alcohols are also presented.
