Core Level Spectroscopy
Creation and Decay of Core
Core level spectroscopy pro
vides a method to study the chemical
state, local geometric structure, nature of chemical bonding, and dynamics
in electron transfer processes centered around one atomic site via the
mechanisms of x-ray induced core hole creation and decay.
How is the ejection of a photoelectron related to the different spectroscopic
can we use these techniques to gain important information about model
Here's an example...
To the right is an illustration of the
local probing character of core
level spectroscopies applied to N2
adsorbed on Ni(100).
The grey area represents the charge density outside the metal surface
with a cut into the molecular adsorbate. Electronic transitions between
and valence ele
ctrons are indicated
