Introduction to quantum mechanics

For one-semester/-year, junior-/senior-level courses in Quantum Mechanics and Quantum Chemistry.This text first teaches students how to do quantum mechanics, and then provides them with a more insightful discussion of what it means. Fundamental principles are covered, quantum theory presented, and special techniques developed for attacking realistic problems. Two-part coverage organizes topics under basic theory, and assembles an arsenal of approximation schemes with illustrative applications.
