Stereochemical Series: $I^{-}<Br^{-}<Cl^{-}<NO_{3}^{-}<F^{-}<OH^{-}<H_{2}O<py<NH_{3}<en<bpy<NO^{2-}<CN^{-}<CO$

This series can be easily explained on the basis of Molecular Orbital Theory...

The splitting pattern also depends on the oxidation state of the metal ion...

Lower the splitting energy higher the wavelength...

Thank you;

Best of Luck;
