3. Given the following spectroscopic data V2 (cm-1) [Fe(H2O).]2+ [Ru(H2O)6]2+ [Co(H20)6]3+ [Rh(H2O).]3+ Vi (cm-1) 10,400 18,870 16,500 25,500 25,640 24,700 32,800 (a) [Fe(H20)6]2+ shows one weak absorption band while [Ru(H2O)6]2+, [Co(H20)6]3+ and [Rh(H20)6]3+ show two weak absorption bands. Suggest the origin of these electronic transitions. (b) Explain the intensity of these bands based on selection rules. (c) With the aid of the Tanabe-Sugano diagram, assign the transitions and determine the values of A, for all the complexes, and B for [Ru(H20)6]2+, [Co(H20)6]3+and [Rh(H20)6]3+. (d) Rationalize the observed differences in Ao.
