[Post lab Q]: The H NMR spectra of carvone and the epoxidation product(s) are extremely complicated, so we've only given you partial spectra (from δ 3.0 - 7.0 ppm), showing the double bond regions. There are three peaks in this region in the carvone spectrum, corresponding to Ha, Hb and Hc.

Aug 10, 2020 Unlike 1H-NMR signals, the area under a 13C-NMR signal cannot be used to determine the number of carbons to which it corresponds. This is The goals of this experiment are to obtain this isomer, determine its structure using NMR and IR, and draw a multi-step mechanism for its formation. The Carvone is a monoterpene chemical constituent present in Dill and Spearmint essential oils. It contains a ketone functional group and a chiral carbon in its Synonyms: R-(L)-Carvone, 6,8,9-PARA-MENTHADIEN-2-ONE. Uses: Substance isolated from spearmint oil. Used in toothpaste.

The product is identified through interpretation of the [superscript 13]C NMR and DEPT spectra are obtained on an Anasazi EFT-60 at 15 MHz as neat samples. A guided-inquiry approach is used to aid the students Download the 1 H NMR spectrum for carvacrol and carvone from the website. For carvacrol, list the major peaks, chemical shifts and the specific protons in the structure of carvacrol that give rise to each peak in the spectrum. Do the same for the carvone spectrum.

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.
