Course description and aims

Light absorption and emission are important concept to understand photochemistry. In this course, we learn about light and its interaction with molecules in terms of classical electromagnetism and quantum mechanics. Examples of light absorption spectrum are explained with electronic state and oscillator strength. Later part of this course is about emission from high temperature, light, and chemically excited states. Inorganic materials are also described not only for organic molecules. Mechanism of laser also described in order to apply for measurements and reactions.
This course is for the students without back ground of photochemistry and photo physics. Knowledge and ability acquired through this course will help students enjoy photochemisty and photophysics in the future.

Student learning outcomes

By the end of this course, students will have the following abilities:
1) To describe light absorption by molecules in terms of classical electromagnetism and quantum mechanics.
2) To explain the relation between light absorption by light and electronic states of a molecule.
3) To explain principles and applications of luminescent mechanism.
4) To explain principles of laser.


electronic state of molecules, Born-Oppenheimer approximation, Frank-Condon principle, thermoluminescence, photoluminescence, chemiluminescence, laser

Competencies that will be developed

Specialist skills Intercultural skills Communication skills Critical thinking skills Practical and/or problem-solving skills

Class flow

At the beginning of each class, the previous lecture is reviewed. At the end of class, contents of the lecture is summarized. 'Required learning' is needed to be completed outside of the classroom for preparation and review purposes.
