Electronic spectra in coordination chemistry

The most intense absorption band in the visible spectrum of [Mn(H20)6}2+ is at 24,900 cm-1 and has a molar absorptivity of 0.038 mol -1 cm-1. What concetration of [Mn(h20)6]2+ would be necessary yto give an abosorbance of 0.10 in a cell of path length 1.00

Electronic spectra in coordination chemistry

For the isoelectronic series[V(CO)6]-, Cr(CO)6, and [Mn(Co)6]+, does the energy of the metal to ligand charge-transfer bands increase or decrease with increasing charge on the complex? Why?

Electronic spectrain coordination chemistry

An aqeuous solutino of Ni(No3)2 is green.Addition of aqueous solution Nh3 causes the color of the solution to change blue. If the ethylenediamine is added to the green solution,the color changesto violet. What causes the colors of these complexes, how do these colors relate to the epected positions of these ligands in the spectrochemical series?
