Carvone is a member of a family of chemicals called terpenoids. Carvone is found naturally in many essential oil s, but is most abundant in the oils from seeds of caraway ( Carum carvi ), spearmint ( Mentha spicata ), and dill .

The proton NMR spectra of carvone and carvacrol will also allow the product of this reaction to be distinghuished from the starting material. The proton NMR spectrum of carvacrol should contain characteristic peaks in the aromatic region of the spectrum that correspond to the three aromatic protons.

S-(+)-Carvone is the main component of caraway oil and dill, with an odor resembling these herbs. The other isomer (R-(−)-carvone) occurs at high concentrations (70-80%) in spearmint oil and is also the major component responsible for its aroma. Unlike proton nmr spectroscopy, the relative strength of carbon nmr signals are not normally proportional to the number of atoms generating each one. Because of this, the number of discrete signals and their chemical shifts are the most important pieces of evidence delivered by a carbon spectrum. Structure, properties, spectra, suppliers and links for: (+)-(S)-Carvone, 2244-16-8. In C-13 NMR, you cannot draw any simple conclusions from the heights of the various peaks.

The proton NMR spectrum of carvacrol should contain characteristic peaks in the aromatic region of the spectrum that correspond to … NMR and IR spectra of carvone are available at the course web page (see News section). It is worthwhile understanding these spectra. Partly so that you won’t be misled by any carvone “impurity” that might be present in your product mixture, and partly because understanding the carvone spectra may help you work out the structure of the isomer.

I cannot work out this 1H NMR spectra of d(+) carvone. The peaks have (from left to right) the relative intensities 1, 2, 5 and 6. This adds up to the 14 protons that carvone has, but apart from that I cant work out which peaks correspond to which proton environments.

(R)-(−)-Carvone is a monoterpenoid. Its ozonolysis in the gaseous phase has been proposed. Aldehydes (formaldehyde) and biradicals were obtained as the major products. It participates in the diastereoselective synthesis of homochiral octalones.
