Niels Bohr’s 1913 model explaining discrete energy levels in atoms. Wave-Particle Duality: Louis de Broglie’s hypothesis ( ) that particles exhibit wave-like behavior. 2. Mathematical Framework
Quantum chemistry is a theoretical approach to understanding the behavior of molecules and their interactions. It is based on the principles of quantum mechanics, which describe the behavior of particles at the atomic and subatomic level. In quantum chemistry, the Schrödinger equation is used to solve for the wave function of a molecule, which provides information about its energy, structure, and properties. quantum chemistry lecture notes pdf
