Infrared Spectra in Oxide Nanocomposites/Minerals

This chapter provides IR spectral range. The chapter provides IR theoretical importance and its application to analyze the oxide materials. In the theory, energy levels in molecules, different vibrational modes in molecules, and overtones and harmonics are discussed. Different phase sample preparation procedure is described in brief. Various forms of IR spectra and where they employed to analyze the compounds are given. The applications are mainly concerned to nanoferrites, and molecules and minerals. These applications are used to identify the structure, hydroxyls, carbonate ions, silicates, oxides and hydroxides, sulfides, and sulfates. Special attention is given in thin film metrology how IR spectra will be useful to analyze the structure of the film. Effort is made in the usage of IR in environmental studies.
