FT-IR offers a unique method of inorganic compound speciation. Particularily in environmental samples, inorganic information has previosuly been limited to elemental or at best anion/cation information. Using FT-IR, a relatively small amount of sample (about 1 mg) can yield inorganic compound identifications. Of central importance to this technique is the availability of a good computerized reference library of pure inorganic compounds in common hydration states. This library should cover both mid- and far IR. In our laboratory, this library is being amassed using X-ray crystallography to comlement infrared results. A computer search system for the identification of inorganic compounds in mixtures has been developed which uses the above library as well as spectral knowledge of the user. Second derivative spectra are used to establish exact peak frequencies. The combination of good reference spectra and the ability to locate the exact position of overlapping bands by the use of the 2nd derivative, allows the identification of specific inorganic compounds in complex mixtures.
