The analysis
The retrieved literature consistently demonstrates through spectroscopic and computational methods that both lanthanide 4f and actinide 5f orbitals contribute significantly to metal-ligand covalent bonding, supporting the claim without contradictory evidence.
Computational modeling of lanthanide and actinide complexes indicates that valence f- and d-orbitals engage in covalent interactions with ligand donor functionalities.
Quantum-chemical bonding analysis of isostructural lanthanide and actinide amidinates highlights increased covalency within the actinide series, evidenced by greater 5f orbital occupation.
Quantum chemical calculations show that actinide complexes feature specific f-electron polarization and backbonding contributions driving covalent character.
Density functional theory and population analyses confirm that increased 5f-orbital participation contributes significantly to shortened and more covalent metal-ligand bonds in actinide complexes.
Quantum chemical methods demonstrate that actinide-ligand interactions involve orbital contributions from 5f states that govern bonding trends across the series.
