WebSep 11, 2015 · The nephelauxetic (meaning literally "cloud expansion" from Greek) effect is a common term to describe delocalization of the outer d orbitals of impurity ions because of formation of chemical bonds with ligands. WebOct 1, 2024 · To explain the nephelauxetic effect, Morrison [17] suggested that a 4f electron will polarize the ligand electrons leading to energy lowering. In fact it describes a correlated motion between the 4f electron and the ligand electrons.
