| Summary: | Complete assignments of the <sup>1</sup>H NMR chemical shifts for monoterpenes, borneol, and isoborneol, and their derivatives in which the secondary hydroxy group is protected with an acetyl group or a benzoyl group, have been made in CDCl<sub>3</sub> and C<sub>6</sub>D<sub>6</sub>. Upon the protection of the hydroxy group with the carbonyl functional groups, or acetyl or benzoyl groups, many protons constituting the bicyclic ring exhibited downfield and upfield shifts in the chemical shift values, aiding in the unambiguous assignments of protons and carbons. |
