The eigenvalues are the energies of the ground and some electronically excited states.

Particular emphasis has been given to electronically excited states, molecular spectra and photochemistry.

A Rydberg molecule is an electronically excited chemical species.

He is particularly interested in electronically excited states and the response of molecules to light.

These method exist for the calculation of electronically excited states of polyenes, both cyclic and linear.

Light is emitted because the reaction forms oxyluciferin in an electronically excited state.

The energy of the electronically excited state is given off to vibrational modes of the molecule or phonons.

There is only a strict relationship between the two in monatomic ideal gases (and with no low-lying electronically excited states).

Currently, Prof. Krylov leads a research group focused on theoretical modeling of open shell and electronically excited species.

(For B also, a double prime indicates the ground state and a single prime an electronically excited state.)
