Spectroscopy is broadly defined as the use of light to study the composition and structure of matter.
Spectroscopy is broadly defined as the use of light to study the composition and structure of matter. As light interacts with an object, spectroscopic instruments measure the selective absorption, emission, or scattering of light by matter. Scientists can then use these measurements to determine specific characteristics of a desired material such as the presence of toxic molecules in water, the effectiveness of a drug, or the structure of a target protein.
Modern applications of spectroscopy go beyond the visible light spectrum and utilize the entire electromagnetic spectrum, spanning from gamma and x-rays, ultraviolet and infrared light, to radio waves. The term spectroscopy has even come to refer to measurements that do not involve any form of electromagnetic radiation. For example, the most prominent spectroscopic technique today, mass spectrometry, involves the analysis of molecular fragments released upon vaporization of a sample.
