Fourier Transform Infrared Spectroscopy: Fundamentals and Application in Functional Groups and Nanomaterials Characterization
Infrared spectroscopy is an extremely important instrumental tool in applied and basic sciences for the determination of various functional groups. In this chapter, we have described in detail the range of electromagnetic spectrum, IR regions, and basic principal by which IR radiations interact with matter. The identification of various functional groups in different class of organic compounds is also described. A detailed instrumentation is given in later section. The FTIR-ATR and its instrumentation were also explained, and finally its application for the characterization of nanomaterials is described. The application of IR spectroscopy in various fields is explained in detailed. It is noteworthy the IR is only active for that molecule which has a net dipole moment. A molecule and pure element have zero dipole moment, therefore, are not active in IR spectroscopy.
