Determination of charge-transfer electron transitions in tungsten tetrahydride complexes stabilized by organophosphorus ligands by X-ray photoelectron and UV absorption spectra

Abstract

A change in the energy of the long-wave transition in the UV absorption spectra of tetrahydride complexes WH.~L 4 is equal to the change in the energy of the internat 2p-levet of phosphorus. Based on the correlation determined, the electron transitions related to the !ong-wave absorption bands in the UV spectra were assigned to the charge-transfer transitions from the organophosphorus ligand to tungsten.
