Chem120A Notes 8/27/08 Quantum Chemistry → Statistical Mechanics → Thermodynamics and Chemical Kinetics (120A) (120B) (120B) → Schrödinger equation can be solved explicitly for only one system (the Hydrogen Atom) →Approximations must be made to solve other, more complex, systems. Motivations for developing quantum mechanics →Blackbody Radiation, Photoelectric Effect, Rydberg Equation, etc. →Louis de Broglie (Nobel Prize 1929) developed the de Broglie wavelength, which describes the wavelength of all particles p h = λ ; where h is Planck’s constant, is the wavelength, and p is the linear momentum →demonstrates wave/particle duality (i.e. All particles have an associated wavelength) →Davison-Germer diffraction experiments demonstrated the de Broglie wavelength, by passing particles through a double slit, and observing the wave-like properties of those particles Classical Wave Theory of Light 2 2 2 2 2 ) , ( 1 ) , ( t t x V x t x Ψ - = Ψ ; Ψ → function of space (x) and time (t)
