WebJul 14, 2024 · A clever way of picking out the -OH peak. If you measure an NMR spectrum for an alcohol like ethanol, and then add a few drops of deuterium oxide, D 2 O, to the solution, allow it to settle and then re-measure the spectrum, the -OH peak disappears! By comparing the two spectra, you can tell immediately which peak was due to the -OH group. WebFor nmr purposes, this small energy difference (ΔE) is usually given as a frequency in units of MHz (10 6 Hz), ranging from 20 to 900 Mz, depending on the magnetic field strength …
