The proposed mechanism was either direct excitation of the dye molecules or excitation of electrons.

Shock is a transient physical excitation.

The Higgs boson is an excitation of the Higgs field.

It takes an excitation of the Higgs field to produce the Higgs boson.

The process of generating a magnetic field by means of an electric current is called excitation.

Excitation energy is lost within the atmosphere by the emission of a photon, or by collision with another atom or molecule oxygen emissions green or orange red, depending on the amount of energy absorbed.

Voodoo acolytes in a state of trance handling burning embers with impunity, a rather astonishing demonstration of the ability of the mind to affect the body that bears it when catalyzed in the state of extreme excitation.

Auroral particles The immediate cause of the ionization and excitation of atmospheric constituents leading to auroral emissions was discovered in 1960, when a pioneering rocket flight from Fort Churchill in Canada reveealed a flux of electrons entering the atmosphere from above.
