Syllabus
Course overview and goals
The course teaches the fundamentals of quantum theory and its applications to biological systems, including the electronic structures and spectroscopic properties of biological molecules. Quantum theory is important for understanding nature, and is essential for the study not only of life science, but also of other specialized sciences and engineering. Students learn the laws governing the motions of electrons in atoms and molecules together with the mathematical description of such motions, that is, the Schrödinger equation. They will be able to solve the equation for simple process (one- or two- dimensional translational, rotational and vibrational motions), and the electronic structures of diatomic molecules and the pi-electron systems of small conjugated double bond compounds. Together with quantum theory, this course provides brief reviews of classical mechanics, wave mechanics, electromagnetism and optics, which are helpful for understanding the origin of quantum theory. This course also provides a brief introduction to computer simulations that are currently indispensable for investigating biological molecules. By the end of this course,students will understand that quantum theory is essential to interpret and predict many spectroscopic data including ultraviolet/visible, fluorescence, vibration spectra.

Class flow
At the beginning of each class, solutions to exercise problems that were assigned during the previous class are
reviewed. Towards the end of class, students are given exercise problems related to the lecture given that day to solve.
To prepare for class, students should read the course schedule section and check what topics will be covered.
