Despite its importance, quantum chemistry is a challenging field, both theoretically and computationally. The Schrödinger equation, which is the fundamental equation of quantum mechanics, is difficult to solve exactly for systems with more than a few electrons. Therefore, various approximations and numerical methods have been developed to solve the equation approximately.
