If the metal is in low oxidation state and the ligands contain empty orbitals, then:
A) Metal-to-ligand charge-transfer transitions are observed.
B) Ligand-to-ligand charge-transfer transitions are observed.
C) Ligand-to-metal charge-transfer transitions are observed.

Question

Quizplus · Accepted Answer

Metal-to-ligand charge-transfer transitions occur when the metal is in a low oxidation state and the ligands contain empty orbitals. This is because the metal can donate electrons to the ligands, which then become excited.
