  2. review of Lz operator, eigenfunction, eigenvalues rotational kinetic energy traveling and standing waves spherical coordinates definition Laplacian operator Schrödinger’s equation in spherical coordinates separation of angular variables: L2 and Lz differential equations spherical harmonics and eigenvalues vector model of quantum angular momentum radial wavefunctions effective radial potential – centrifugal `force’ radial wave functions hydrogenic orbitals Outline

  3. Spherical Coordinates

  4. Cylindrical vs. Spherical Coordinates Laplacian: Schrödinger Equation: Lz2 / 2I L2 / 2I

  5. Spherical Harmonics L2 Ylm=l(l+1)Ylm s 1 Lz Ylm= m Ylm x, y p z x, y x2+y2, xy xz, yz d 3z2-1 xz, yz x2+y2, xy f …

  6. Vector model of quantized angular momentum l = 0, 1, 2, … m = -1, -l+1, … l-1, l

  7. Radial equation – effective potential

  8. Radial hydrogenic wavefunctions

  9. Putting radial and angular parts together 2p wave
