: This is the fundamental equation of quantum chemistry. The time-independent version is expressed as: Ĥψ=Eψcap H hat psi equals cap E psi Ĥcap H hat is the Hamiltonian operator (representing total energy), is the wavefunction, and is the energy of the system.

Understanding that observables in quantum mechanics (energy, momentum, position) are represented by operators, leading to eigenvalues and eigenfunctions.

| Term | Definition | |------|-------------| | Eigenfunction | Function that satisfies ( \hatO\psi = a\psi ) | | Eigenvalue | The constant ( a ) in the eigenvalue equation | | Hermitian operator | ( \int \phi^ (\hatO\psi) = \int (\hatO\phi)^ \psi ) → real eigenvalues | | Node | Point where wavefunction = 0 (not counting boundaries) | | Degeneracy | Multiple states with same energy | | Tunneling | Particle penetrating a classically forbidden barrier | | Zero-point energy | Lowest possible energy (not zero) due to confinement | | Pauli principle | No two electrons share all four quantum numbers |
