Course description and aims

The purpose of this lecture course: To get the knowledges for understanding the relation between form of molecules and optical data.

This lecture consist of three main subjects
1:Study about the simple model for treating the molecular vibrations
2:Study the relation between group theory and molecular vibrational spectroscopy
3:Understand the molecular structure based on spectroscopic data based on the theoretical model

Student learning outcomes

The ultimate purpose of this lecture is following 2 points:
1:Study about the role of quantum mechanics in the molecular dynamics
2:Based on the basic quantum mechanics combining with group theory, get the knowledges for understanding the relation between molecular structure and spectroscopic data.


structure of molecules, spectroscopy, infrared (IR) absorption, Raman scattering, group theory

Competencies that will be developed

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

Class flow

Lecture includes a few times training test based on simple problems.

Class 13 Discussion utilizing realistic example 3: the realistic way to determine the structure of water and other moleclues utilizing spectroscopic data. Lets's confirm the relation between structure of water/other molecules and spectroscopic data.
Class 14 Summary Comparison with the data of experimental course

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.


Physical Chemistry, D . Ball, Brooks/Cole Thomson Learning 2003

Reference books, course materials, etc.

no textbook is specified

Assessment criteria and methods

Following three points will be evaluated: 1:Advanced knowledges about molecular vibration based on the quantum mechanics, 2:Classification of molecular structures utilizing group theory, 3: Knowledges and techniques necessary for making clear the molecular structure based on spectroscopic data.

Evaluation will be made by the reports about the training problems set in the lecture course and also by final one. The final report (report during class room) will occupy 80 % (20%) of the evaluation.
