Course description and aims
This course is designed to provide students the opportunity for learning fundamental aspects of quantum chemistry, with which we can understand all the chemical phenomena in terms of microscopic fundamental laws.
The course is organized to develop students' abilities in the following four subjects:
1) Understanding fundamentals of quantum mechanics and the characteristics of wave functions,
2) Utilizing the quantum-mechanical description of 1D/2D/3D motion of particles.
3) Understanding the motion of electron in atoms in terms of the aforementioned fundamental knowledge in quantum mechanics,
4) Utilizing approximation methods in quantum mechanics to establish the quantum-mechanical description of electronic states and chemical bonding in molecules.
Student learning outcomes
Students will acquire the following two skills by taking this course.
1) Gain an understanding of the basic principles of quantum mechanics, and apply them appropriately to basic problems.
2) Gain a basic understanding of state of motion in atoms and molecules, and chemical bonding based on the knowledge of quantum mechanics.
Keywords
Wave functions, Quantum numbers, Electronic states, Molecular orbitals, Chemical bonding

Out-of-Class Study Time (Preparation and Review)
To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 100 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.
