ex·cit·ed state ( k-s  td)n. The condition of an atom or molecule after absorbing energy from exposure to light, electricity, elevated temperature, or chemical reaction, and which may be a necessary prelude to a chemical reaction or to the emission of light. |
excited state
[eksī′tid]
Etymology: L, excitare, to rouse, status
(in chemistry and physics) an energy level of a system that is higher than the ground state. The system decays to the ground state and emits the energy difference, usually in the form of photons.
state
condition or situation.
excited state
the condition of a nucleus, atom or molecule produced by the addition of energy to the system as the result of absorption of photons or of inelastic collisions with other particles or systems.
ground state
the condition of lowest energy of a nucleus, atom or molecule.
refractory state
a condition of subnormal excitability of muscle and nerve following excitation.
resting state
the physiological condition achieved by complete rest for at least 1 hour.
steady state
dynamic equilibrium.
