【 摘 要 】

Transition metal complexes intercalated in layered double hydroxides have a different electronic structure as compared to their free state owing to their confinement within the interlayer gallery. UVâ€�?�Vis absorptions of the intercalated complex anions show a significant shift as compared to their free state. The ligand to metal charge transfer transitions of the ferricyanide anion show a red shift on intercalation. The ferrocyanide ion shows a significant blue shift of ð‘�?�–ð�?��?? bands due to the increased separation between ð‘�?_2g and ð‘�??_g levels on intercalation. MnO$^{-}_{4}$ ion shows a blue shift in its ligand to metal charge transfer transition since the non-bonding ð‘�?₁ level of oxygen from which the transition arises is stabilized.
