| In the first part of this brief review, attempt has been made in elucidating the
simple and salient features of Ligand Field Theory. As a typical example, the absorption
spectra of [V(H20)6] 3+ has been taken to calculate Racah parameters B and C, and
the Ligand Field strength Ll.
The colour imparted by iron in glass is of potential importance from technological
point of view; the absorption spectra of Fe (II) and Fe (III) in different simple glasses
have been discussed in terms of Ligand Field Theory in the second part of this review.
The ultraviolet absorption of Fe (III) and Fe (II) (charge transfer bands) have also been
discussed in terms of qualitative Molecular Orbital Theory. |
