Solvent effect Our choice of solvent can affect the appearance of a spectrum-can result in band broadening. Example Vapor phase spectrum Here we have no solvent and minimal interaction between the molecules

UV/Vis absorption Absorption by inorganics Similar to organics-notably for nitrates. You can also see some absorbance for species with partially populated d orbitals. Most dramatic absorptions are observed for transition metal complexes.This is a result of the interaction of the ligand with the metal's d orbitals
UV/Vis absorption Absorption by inorganics For most transition metals,we have partially populated d orbitals. For a free ion,the d orbitals are all at the same energy.However,the orbitals are not identical. Interaction with a ligand will effect some orbitals more than others
UV/Vis absorption The type and degree of splitting depends on the ligand and geometry of the complex that is formed. octahedral tetrahedral square planar
