: It is often used to model conjugated molecules, like polyenes (e.g., -carotene). Harmonic Oscillator | Paper Title | Authors / Journal |

Nuclei are thousands of times heavier than electrons and move much slower. The Born-Oppenheimer approximation states that we can freeze the nuclei in place and solve for the wavefunctions of the fast-moving electrons independently. The nuclear positions then act as static parameters rather than variables. The Variational Principle It adds small correction terms (first-order

Used when a complicated system is only slightly different from a system that is already solved. It adds small correction terms (first-order, second-order) to the known energy and wave function, forming the basis for methods like Møller–Plesset perturbation theory (MP2). 4.
