Web30. jan 2024 · The infrared spectrum for an alcohol: Ethanol The O-H bond in an alcohol absorbs at a higher wavenumber than it does in an acid - somewhere between 3230 - 3550 cm -1. In fact this absorption would be at a higher number still if the alcohol isn't hydrogen bonded - for example, in the gas state.

WebThe excitation and emission spectra of the three phenolic compounds are very similar because of their analogical structure. The intensity of the spectrum has a good linear relationship with the concentration when the solution concentration is between 0.02 and 1.0 mg x L(-1), and the limits of detection can reach at 1 microg x L(-1). Webuse spectral data (infrared, NMR, mass spectroscopy) to assist in the identification of an unknown alcohol or phenols. You may use tables of characteristic absorptions as an aid to accomplishing this objective.
