will yield an expectation value for the energy that is greater than or equal to the true ground-state energy E0cap E sub 0 The square of its absolute value, : This

Exact solutions are impossible for systems with more than one electron due to electron-electron repulsion. Quantum chemists rely on systematic approximations to solve the electronic Schrödinger equation. The Born-Oppenheimer Approximation

If you find a PDF on a generic site (like a student repository or a forum), you must verify it before trusting the math. Follow this checklist:
