Lecture
This lecture covers the basics of basis sets in quantum chemistry, including the differences between STOs and GTOs, advantages and disadvantages of each, and the use of contracted Gaussian-Type Orbitals. It also explains the types of basis sets, such as minimal, double-zeta, and triple-zeta, and introduces the Gaussian product theorem for simplifying integrals. Examples of benzene molecular orbitals and atomic wave functions are provided.
