Spectroscopy refers to a plethora of different techniques that employ radiation in order to obtain data on the structure and properties of matter, which is used for solving a wide variety of analytical problems. In short, spectroscopy deals with measuring and interpreting spectra that arise from the interaction of electromagnetic radiation (a form of energy propagated in the form of electromagnetic waves) with matter. It is concerned with the absorption, emission, or scattering of electromagnetic radiation by atoms or molecules. Since its inception in the second half of the 19th century, the technique has developed to include every region of electromagnetic spectrum and every attainable atomic or molecular process. Consequently, most engineers and scientists work directly or indirectly with spectroscopy at some point in their career.
- The learners should be able to apply the different spectroscopic methods to solve problems based on it, spectral data for explaining important organic reactions and functional transformations.
