Infrared Absorption Spectra

Some physical properties, such as color, melting point, moisture content, loss in weight on heating, solubility, and extinction coefficients, of five commercially available bilirubins have been determined and compared. The visible and infrared absorption spectra of the bilirubins also were recorded and are discussed.
