How to interpret a PES graph?

A PES spectrum is a graph of photoelectron count vs. binding energy. The peaks in a PES spectrum correspond to electrons in different subshells of an atom. The peaks with the lowest binding energies correspond to valence electrons, while the peaks with higher binding energies correspond to core electrons.

How do you calculate photoelectron spectroscopy?

PES involves a given energy of photon to ionize a molecule. As the excess energy, will be in the form of kinetic energy, is calculated by the photoelectron spectrometer it is possible to calculate ionization energy of a molecule, by rearranging the following equation: Ek=hν−EI, to solve for EI, ionization energy.

How to interpret electron configuration?

The tiny superscripts say how many electrons live in each orbital, the letters represent the orbitals that are available, and the big numbers say which energy level the orbitals are found in.

What does PES tell us?

Price Elasticity of Supply (PES) measures the responsiveness of the quantity supplied of a good to changes in its price. PES helps us understand how much the quantity supplied changes when the price changes.

How do you read a PES graph?

When reading a PES graph, the x-axis refers to the energy required to remove the electron and is read backwards meaning that closer to the y-axis means more energy and further away is less energy. The units frequently used are binding energy, MJ/mol, electron volts (eV), or ionization energy.

What is the photoelectron spectrum of HF?
