Definition of Spectroscopy
Spectroscopy is the study of the absorption as well as the emission of light rays and other forms of radiation by matter. Both the phenomena of absorption and emission depends upon the wavelength of the radiation. Spectroscopy also deals with the study of interactions present between the particles such as electrons, protons, and ions. The techniques of spectroscopy are applied in almost all fields of science and technology.
Radiofrequency spectroscopy is employed in magnetic resonance imaging through which the soft tissues of the body can be visualized. The internal structure of the atom can also be determined by spectroscopy. Optical spectroscopy is used in the identification of the chemical composition of matter and the physical structures can also be determined through it.
