1
Bohr Model of the Hydrogen Atom Postulates Certain orbits are stationary. Photon emission occurs upon orbital trans. Angular momentum is quantized.

2
Matter Waves Louis de Broglie (1892 – 1987) = h/p

3
Constructive InterferenceDestructive Interference (Standing Wave) Hydrogen Atom

4
Towards a Wave Equation Classical Wave Propagation

5
Hamiltonian Mechanics William Hamilton (1805 – 1865) H = T + V

6
Now What? Erwin Schrodinger (1887 – 1961) The wave function contains all possible information about a system, so instead of speaking of “the state described by the wave function ,” we simply say “the state .” Quantum Chemistry by Ira N. Levine

7
What is the Wave Function? Max Born (1882 – 1970) Quantum mechanics does not say that an electron is distributed over a large region of space as a wave is distributed. Rather, it is the probability patterns (wave functions) used to describe the electron’s motion that behave like waves and satisfy a wave equation. Quantum Chemistry by Ira N. Levine
