Photochemically-induced perturbation of the 1A ⇌5T equilibrium in Fe11 complexes by pulsed laser irradiation in the metal-to-ligand charge-transfer absorption band

Abstract

Rapid perturbation of the ¹A ⇌⁵T equilibrium in several Fe¹¹ complexes occurs upon irradiation in the metal-to-ligand charge-transfer absorption region of the low-spin state, providing primary evidence for the formation of a ⁵T ligand field state from the initially populated charge-transfer state and permitting study of the dynamics of the spin change in a wide range of solvents.
