Webb[1] [2] In physical and analytical chemistry, infrared spectroscopy (IR spectroscopy) is a technique used to identify chemical compounds based on the way infrared radiation is absorbed by the compound. The absorptions in this range do not apply only to bonds in organic molecules. WebbThe H-bonding to the carbonyl may be observed by a shift of the C=O stretching mode (decrease of the wavenumber), but the change may be small depending of the interaction, and also because the...

Webb5 mars 2024 · The infrared spectra of certain 1,2-diols (glycols) are interesting in that they show absorption due to intramolecular hydrogen bonding. These usually are fairly sharp bands in the region 3450cm − 1 to 3570cm − 1, and, in contrast to bands due to intermolecular hydrogen bonding, they do not change in intensity with concentration.
