Course description and aims

[Summary of the lecture] This course covers fundamental concepts of group theory and its application to inorganic chemistry, in particular to determine the physical and chemical properties of a molecule on the basis of its structure.
[Aim of the lecture] The concept of symmetry is of the greatest importance in inorganic chemistry, since it helps to determine the physical and chemical properties of a molecule, such as mode of vibration and molecular orbitals, without any complicated calculations. This course focuses on the use of the group theory to the classification of the molecules, constructing molecular orbitals, and analyzing molecular vibrations and their selection rules. Students understand that symmetry considerations can be used to predict physical and chemical properties of a molecule.

Student learning outcomes

At the end of this course, students will be able to:
1) explain the symmetry operations, which leaves a molecule apparently unchanged and associated symmetry elements.
2) determine the point groups of molecules on the basis of their structure.
3) explain the physical and chemical properties of a molecule by the use of character tables.
4) construct of molecular orbitals from symmetry adapted linear combinations of atomic orbitals.

Keywords

symmetry, symmetry operations, symmetry elements, point groups, character tables, symmetry labels, symmetry adapted linear combinations of atomic orbitals, molecular vibration, molecular orbital

Competencies that will be developed

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

Class flow

This lecture will proceeds in the following order: (1) the basic concepts of the group theory (2) assignment of a molecule to a particular point group (3) prediction of physical and chemical properties of a molecule by the use of character tables, such as analyzing molecular vibrations and their selection rules, construction of molecular orbitals by using symmetry adapted linear combinations of atomic orbitals. In the last day, final examination is set to assess the level of understanding.

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.
