Excited state

In quantum mechanics, a stationary state of higher energy than the lowest stationary state or ground state of a particle or a system of particles. Customarily, only bound stationary states, which generally are at most denumerably infinite in number, are spoken of as excited, although the formal quantum theory often treats the noncountable unbound stationary states on an equal footing with the bound states. See Ground state, Metastable state

This suggests that the photophysical behavior of these compounds should present subtle differences, what is corroborated by the analysis of excited electronic states and molecular orbitals.
The planned experiments will be directed toward understanding the effects of static and time-dependent electric and magnetic fields, and blackbody radiation fields on slow dissociation processes that occur in highly excited states of N2, O2 and NO, investigations of collisional energy transfer processes, and studies of the role that these excited electronic states play in the evolution and reactivity of atmospheric plasmas incl
