... molecule. Absorption bands due to overtones of OH stretching vibrations fall into three distinct well-resolved giioupa: (a) water, (b) alcohoils and Phenols, and (c) carboxylic acids and hydroperoxides. This permits quantitative determination of some hydroxyl types in the presence of others. Near-infrared...
