Differentiate between binding energy and kinetic energy in PES.
Binding Energy: Energy required to remove an electron. Kinetic Energy: Energy of the ejected electron after removal.
What are the three main steps of Photoelectron Spectroscopy (PES)?
- Shine light on a sample. 2. Electrons are ejected if the light has enough energy. 3. Measure the kinetic energy of the ejected electrons.
In a PES spectrum, what information do the X and Y axes provide?
X-axis (Binding Energy): Energy needed to remove an electron. Y-axis (Intensity): Number of electrons in that subshell.
What does the peak height on a PES spectrum indicate?
The number of electrons in that energy level (subshell).
What does the peak position on a PES spectrum indicate?
The energy level (binding energy) of the electron.
