Since your request is slightly ambiguous (do you want actual lecture notes or research papers that cite/use such notes? ), I have broken this down into two categories.

: It solves the Schrödinger equation in spherical coordinates rather than Cartesian coordinates. quantum chemistry lecture notes pdf

Nuclei are thousands of times heavier than electrons and move much slower. The Born-Oppenheimer approximation states that we can freeze the nuclei in place and solve for the wavefunctions of the fast-moving electrons independently. The nuclear positions then act as static parameters rather than variables. The Variational Principle Since your request is slightly ambiguous (do you
