Different energetic beams can be used for excitation of solids with the creation of holes in electronic levels: photons, ions, electrons. In this chapter only the electron impact excitation will be taken into account, but many of the conclusions can easily be extended to other excitation modes.

Electronic Spectroscopy by Electron Spectroscopy
Annual Review of Physical Chemistry, 1969Confronted with the stupefying flow of new information in the field of electronic spectroscopy, we have selected for review here three closely related topics likely to be less familiar to many of the readers of A nnual Reviews of Physical Chemistry than conventional spectroscopic methods.

Electronic and Vibrational Spectroscopy of CsS
The Journal of Physical Chemistry A, 2018Using multi configurational ab initio methodologies, we compute the potential energy curves (PECs) of the lowest electronic states of the diatomic CsS. These computations are performed using internally contracted multireference interaction configuration including Davidson correction (MRCI+Q) with and without considering spin-orbit effects.

This chapter pays special attention to the Franck–Condon principle, which asserts that electronic transitions occur within a stationary nuclear framework. It explains how the Franck–Condon principle is used to show how electronic transitions are accompanied by vibrational transitions and results in broad bands of absorption.

Journal of Applied Physics, 1946
According to Einstein, the electrons leave a photo-electric surface with an initial velocity proportional to the frequency of the impinging radiation. Consequently, when a sawtooth potential is applied to a photoelectric cell, illuminated by a monochromatic light, the current flow starts at a threshold potential corresponding to the wave-length of the ...

Spectroscopy as discussed so far has been for electromagnetic radiation interacting with solids. According to the last chapter a beam of charged particles will also interact with the electronic system of the solid and will thus be subjected to an energy loss.

This chapter covers spectroscopy involving the excitation of an electron from one state to another. It talks about how electronic transitions occur at longer wavelengths and are often seen in the visible state as the separation of electronic energy levels of open-shell molecules is typically small.
