Intro to Electronic Structure Theory Part 2

We discuss the Born-Oppenheimer approximation and potential energy surfaces

Finally a beautiful series of lectures on QM: well explained, clear, without jargons, straight to the important points and explained in such a way one can follow through. The books I have used to far at a certain point they all get lost into math and do not really guide you through.

So True!!

Thanks Dr, Sherill for the simplification of BOA and PES.

7:10 Can I ask why E_{el}(R) on the right of the equation instead of E_{el}(r;R) or E_{el}(r)? The equation slight depends on R. Why is the R still in the E_{el}? Thank you, Prof. Sherrill.

The electronic energy is computed by integrating over the electronic coordinates (r) ... so these degrees of freedom are already integrated out. However, you will get a different electronic energy at each nuclear configuration R, so the dependence on R remains
