Before approaching this topic, students should:

• Know how to find the possible eigenstates and energies for an electron in a two-atom potential well.
• Be able to represent the possible eigenstates for a two-atom potential well using an envelope function for the coefficients.
• Know the general shape of the ground state wave functions for a single potential well.
• Have some experience in quantum mechanics, including using the energy eigenvalue equation and Schrodinger's equation.
• Understand how to represent quantum states using bra-ket notation or function notation.
• Be able to comfortably transition between bra-ket notation and function notation.
• Have experience with the properties of observables.
• Know how to find the eigenvectors and eigenvalues for a matrix.
