The 3Δ‐deuterium isotope effects of partially and fully deuteriated tert‐butyl groups on the 13C NMR spectra of tert‐butylbenzene and derivatives are discussed in detail. It is shown that they correlate with the chemical shift of C‐1 of the aromatic ring. It has been demonstrated that when deuterium is replaced with some other substituents, the SCS values of these substituents show a parallel behaviour
详细讨论了部分和完全氘化的叔丁基对叔丁基苯及其衍生物的 13C NMR 谱的 3Δ-氘同位素效应。结果表明,它们与芳环 C-1 的化学位移相关。已经证明,当氘被一些其他取代基取代时,这些取代基的 SCS 值显示出与氘同位素效应相似的行为。结论是,对于所研究的化合物,氘同位素效应和取代基化学位移可以在共同的基础上描述。
