This book presents the theory as well as applications of vibrational spectroscopy with the help of state-of-the-art information. Diverse spheres including chemistry, physics, astronomy, medicine, mineralogy and biology have found use of infrared and Raman spectroscopy. This text provides some instances of the uses of vibrational spectroscopy in supramolecular chemistry, inorganic chemistry, solid state physics and other such fields, including those of molecule-based materials or organic-inorganic interfaces.
