Abstract
Quantum chemistry is offered as an advanced course in chemistry departments of science and engineering. The theory and computation of the LCAO (Linear Combination of Atomic Orbitals) method of Hückel approximation, one of its central themes, is fundamentally related to solving for eigenvalues and eigenvectors of a symmetric matrix. However, it is rarely approached from a linear algebra perspective. Linear algebra is a required course for first-year students, so it is an excellent opportunity for students to use their knowledge of linear algebra. This paper presents a teaching method of LCAO based on linear algebra.
