Description: WebDefinition. Most spectroscopic phenomena arise from the interaction of a molecule with one photon at a time. The molecule may either absorb or scatter the photon; it may also emit a photon. The simplest form of spectroscopy is absorption, which measures how much light of a given frequency is absorbed by a collection of molecules.
