**Prerequisites**- No prerequisite or concurrent.
**Course Enrolment Limitations**- The course is also offered to the students of the fields other than those the course is directly associated with.
**Fields of study the course is directly associated with**- there are 25 fields of study the course is directly associated with, display
**Course objectives**- The aim of the course is to provide understanding of the concepts of molecular and crystal symmetry, symmetry point groups and plane groups, and their applications in vibrational spectroscopy, chemical bond theory, and crystallography.
**Learning outcomes**- Upon completing this course, students will be able: to determine the point group of symmetry for a given molecule; to find a reducible representation and decompose it into its irreducible components; to solve problems in vibrational spectroscopy using character tables; to identify symmetry elements in two-dimensional repeating patterns and assign them plane symmetry groups.
**Syllabus**- 1. Introduction: symmetry in natural sciences including history 2. Symmetry elements and operations. Symmetry contingent molecular properties. 3. The point symmetry groups, classification of molecules. 4. Group, the defining properties, the multiplication table, subgroup, class. 5. Irreducible representations and their characters. 6. Matrix representations of groups, characters. 7. Character tables of irreducible representations. Relationships between reducible and irreducible representations. Degeneracy. 8. Symmetry of molecular vibrations. 9. Applications to chemical bonding. 10. Zero and non-zero values of integrals. Selection rules in spectroscopy. 11. Periodicity in one, two, and three dimensions. Structure, lattice, and unit cells. 12. Symmetry of five plane lattices. Crystallographic point groups, plane symmetry groups. Glide planes and screw axes.
