摘要：

Carbon‐13 chemical shift parameters for equatorial and axial substituents in cyclohexane are reported for methyl, ethyl, isopropyl, methoxy and phthalimido substituents. The usefulness of the alkyl parameters is demonstrated by the agreement between calculated and observed 13C shifts for trans‐1,4‐dialkylcyclohexanes (alkyl = Me, Et, i‐Pr) and for both conformations of cis‐1,4‐dialkylcyclohexanes (alkyl = Me, Et, i‐Pr).
