IR and Raman spectra of eugenol, isoeugenol and methyl eugenol have been obtained in the liquid phase. Vibrational spectroscopic results are discussed in relation to computed structures and spectra of the low energy conformations of these molecules obtained from DFT calculations at the B3LYP/cc-pVTZ level. In der Zahnheilkunde dient Eugenol als schmerzstillendes (nur oberflächlich), antibakterielles und entzündungshemmendes Mittel. Es wird zur Prophylaxe von Pulpitis , zur Behandlung der akuten Pulpitis oder der akuten Parodontitis verwendet.

IR-Spektren werden interpretiert, um aus der Kurve des gemessenen IR-Spektrums die Molekülgestalt herleiten zu können. Dabei werden die verschiedenen Schwingungsvarianten der Moleküle gemessen und daraus auf das Vorhandensein bestimmter Strukturelemente geschlossen. Ein typisches IR-Spektrum reicht von 4000 cm −1 bis 400 cm −1 .

IR (infrared) spectroscopy is useful in organic chemistry because it enables you to identify different functional groups. This is because each functional group contains certain bonds, and these bonds always show up in the same places in the IR spectrum. Functional groups are the portions in an organic molecule that dictate how the molecule will […]

A study of eugenol release and its kinetics model from chitosan-alginate polyelectrolyte complex (PEC) Fourier-transform infrared spectroscopy (FTIR) was.

0.0770 g of eugenol was recovered from 1.032 g of cloves. IR and Raman spectra of eugenol, isoeugenol and methyl eugenol have been obtained in the liquid phase. Vibrational spectroscopic results are discussed in relation to computed structures and spectra of the low energy conformations of these molecules obtained from DFT calculations at the B3LYP/cc-pVTZ level. Although computed differences in vibrational spectra for the different conformers were Figure 3. shows the IR spectrum of octane. Since most organic compounds have these features, these C-H vibrations are usually not noted when interpreting a routine IR spectrum.

Eugenol is a phenylpropanoid formally derived from guaiacol with an allyl chain substituted para to the hydroxy group. It has a role as an allergen, a plant metabolite, a human blood serum metabolite and a sensitiser.

The clean peak indicates that it is a pure sample. The broad peak at 3530.05 cm-1 is indicative of a hydroxyl functional group which would signify that the distillate is eugenol and not eugenol acetate. Shown below is the IR spectrum of eugenol. Highlight the peaks assigned to O-H, C-H and C=C stretching by annotating the spectrum. The IR spectrum of the sample at hand has a clean broad peak at 3530.05 cm-1.
