Lecture 7 Notes: Huckel Theory
In general, the vast majority polyatomic molecules can be thought of as
consisting of a collection of two-electron bonds between pairs of atoms. So the
qualitative pictu

Now that we have treated the Hydrogen like atoms in some detail, we now
proceed to discuss the next-simplest system: the Helium atom. In this
situation, w

For the simple case of the one-electron bond in H2 we have seen that using the
LCAO principle together with the variational principle led to a recipe for
computing some ap

Now that we have obtained the general eigenvalue relations for angular momentum
directly from the operators, we want to learn about the associated wave functions.

Thus far, we have learned that the independent particle model (IPM) gives a
qualitatively correct picture of the eigenstates of the helium atom. What about atoms

In practice, even for systems that are very complex and poorly characterized, we
would like to be able to probe molecules and find out as much about the s
Lecture 3 Notes: Wave Functions
It is a bit awkward to picture the wavefunctions for electron spin because the
electron isnt spinning in normal 3D space, but in some internal dimension that is
