Advanced Inorganic Chemistry

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 C_n, C_nv, D_nh 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.

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 ∆_o from spectra; charge transfer spectra and its application in inorganic & coordination compounds.
