ABSTRACT
The hydroxyl group has been extensively studied in the near-infrared region, particularly with respect to hydrogen bonding. The advantages of longer pathlength cells for liquids and direct analysis of solids have contributed to the utility of near-infrared for hydrogen-bonding studies in a great variety of mixtures and environments. Also, the near-infrared offers a special advantage over the mid-infrared in the measurement of mixtures of water and other hydroxyl-containing compounds because the combination peaks of water and other hydroxyls are well separated from each other in the near-infrared.
