Configurations of an atom or molecule that contain more energy than the ground state.
Excited electronic or vibrational states usually occur following the absorption of radiation of the correct frequency, and are lost by processes such as emission of the radiation (fluorescence) or by reaction. Many electronically excited states are more reactive than the ground state, for example, the first excited state of atomic oxygen, O(1D).
