PRE-LAB QUESTION After consulting sections 5.7 of your text, draw the complete MO diagram for the diatomic molecule, H2. Next to each of the MOs in your diagram, draw a picture that describes the constructive or destructive interference of atomic wave functions and indicate the location of any nodes. Using arrows to represent electrons, place one electron in each of the original atomic 1s orbitals at the edges of your diagram and then show how these electrons pair in the o1s bonding molecular orbital to form the bond that holds these two atoms together.

Electronic Transitions and Spectroscopy

The term “electronic” connotes electron, and the term “transition” implies transformation. In a molecule, the electrons move from a lower to a higher energy state due to excitation. The two energy states, the ground state and the excited state are the lowest and the highest energy states, respectively. An energy change is observed with this transition, which depicts the various data related to the molecule.

Photoelectron Spectroscopy

Photoelectron spectroscopy (PES) is a part of experimental chemistry. It is a technique used in laboratories that involves projecting intense beams of radiation on a sample element. In response, the element ejects electrons for which the relative energies are measured.
