The ultimate goal of quantum chemistry is to explain chemical bonding and molecular geometry. Lecture notes generally cover two competing yet complementary frameworks. Valence Bond (VB) Theory
Ĥ=−ℏ22μ∇2−e24πε0rcap H hat equals negative the fraction with numerator ℏ squared and denominator 2 mu end-fraction nabla squared minus the fraction with numerator e squared and denominator 4 pi epsilon sub 0 r end-fraction
Hydrogen-like atoms, angular momentum, and multi-electron atoms.
Do not just read the PDF. Copy the derivations of the particle-in-a-box energies, the harmonic oscillator ladder operators, and the hydrogen atom radial equation. Muscle memory builds intuition. quantum chemistry lecture notes pdf
