Abstract
Carbon–carbon coupling constants in monoterpene hydrocarbons (3‐carene, α‐pinene and camphene) were investigated. A selective version of the INADEQUATE experiment was used for measurements of the long‐range ^n^J(CC) values. The dependence of the vicinal ^13^C^13^C coupling constants on the dihedral angles and the types of molecular framework involved within the direct coupling path is discussed. The configuration of a heteroatomic derivative from α‐pinene was determined from its ^3^J(CC) values.
