Unit I: 
Symmetry and Group Theory

Symmetry elements and symmetry operations, definitions of group and subgroup, relation between orders of a finite group and its subgroup, conjugacy relation and classes, point group symmetry, schonfiles symbols, representations of group by reducible and irreducible presentations and relation between them (representation for the Cn, Cnv, Dnh etc. groups to be worked out explicitly), character of a representation, the great orthogonality theorem (without proof) and its importance, character tables of C2v and C3v and their use.

Unit II: 
Electronic Spectra of Transition Metal Complexes

Pre requisite: Determination of ground state – Hund’s Rule, spin orbit coupling.

Selection rules for electronic transitions, spectroscopic ground states, splitting of dn terms in octahedral and tetrahedral field; correlation diagrams, Orgel and Tanabe-Sugano diagrams (d1-d9 states); spin cross-over; field strength, spectrochemical series, nephelauxetic series; calculations of Racah parameters; applications of Tanabe-Sugano diagrams in determining Do from spectra; charge transfer spectra and its application in inorganic & coordination compounds.
