Molecular Auger Effect

In the following sections, we first consider molecules for which direct double photoionization seems to dominate, then we present clear examples of molecular Auger effects, and finally we discuss the dissociative double ionization mechanisms that have no counterpart in atoms. 

These lines of results using repair-deficient strains suggest that inner-shell photoabsorption, followed by the Auger effect, more efficiently produces a nonrepairable type of damage than x-rays with other energies. However, studies to find or identify these types of damages at the molecular level have not yet been successful so far.

Studies of molecular adsorption from solution at well-defined solid surfaces is yielding important results. Well-defined surfaces have a simplifying effect on such studies by eliminating many of the structural imperfections which would otherwise complicate the results with a mixutre of adsorption states. Surface analysis methods such as LEED, Auger spectroscopy, EELS, XPS and voltammetry are very well suited to the characterization of surface molecular structure, composition, and bonding. As a result, clear correlations between adsorbed state and surface chemical or electrochemical reactivity are beginning to emerge.
