Organic Chemistry (CHEM311) Fall 2005 Dr. Robert F. Dias So, how about rings? For now we will draw all rings as flat entities. That will change later, but for now, if we want to draw the ring form of hexane (C6H12), we would draw a hexagon… Remember, each kink is a carbon and the hydrogens are there, but we choose not to show them

Quantum Mechanics: The Hydrogen Atom 12th April 2008 I. The Hydrogen Atom In this next section, we will tie together the elements of the last several sections to arrive at a complete description of the hydrogen atom. This will culminate in the de nition of the hydrogen-atom orbitals and associated energies.
7.1 Application of the Schrödinger Equation to the Hydrogen Atom 7.2 Solution of the Schrödinger Equation for Hydrogen 7.3 Quantum Numbers 7.4 Magnetic Effects on Atomic Spectra –The Normal Zeeman Effect CHAPTER 7 The Hydrogen Atom This spherical system has very high symmetry causing very high degeneracy of the wavefunctions
This equation gives us the wave function for the electron in the hydrogen atom. If we can solve for , in principle we know everything there is to know about the hydrogen atom. When we solved Schrödinger's equation in one dimension, we found that one quantum number was necessary to describe our systems. For example, in the Bohr atom, the electron
The Hydrogen Atom Lecture 24 Physics 342 Quantum Mechanics I Monday, March 29th, 2010 We now begin our discussion of the Hydrogen atom. Operationally, this is just another choice for spherically symmetric potential (i.e. Coulomb). Morally, of course, this is one the great triumphs of our time (technically, the time two before ours).

Hydrogen, despite its appearance in every undergraduate quantum mechanics course, is not so paradigmatic. Hydrogen is not even a very typical atom and its “1/n2” Rydberg spectrum is unique, a consequence of a particular special symmetry. It is useful to know
