= Internal conversion (chemistry)
{wiki=Internal_conversion_(chemistry)}
Internal conversion is a non-radiative process in chemistry and physics where an excited molecule transitions to a lower energy state (usually the ground state) without the emission of a photon. Instead of releasing energy as light, the molecule dissipates the energy as vibrational or thermal energy to its surroundings. In more detail, when a molecule absorbs energy and moves to an excited electronic state, it may undergo various relaxation processes to return to a lower energy state.
