This modification of the energy levels of a hydrogen atom due to a combination of relativity and spin-orbit coupling is known as fine structure.
Structure and Bonding: The Hydrogen Peroxide Molecule. Let's examine the hydrogen peroxide molecule, H2O2, in which the oxygen has an oxidation state of -1. Draw the Lewis dot structure of hydrogen peroxide and determine the bond order of the O-O bond. What type of geometry does each the oxygen have?
