Electronic spectra of solid pentakis(dimethylamido)tantalum(V)

Zusammenfassung

The electronic spectra of the complex Ta-V(NMe2)(5) are characterized by amide --> Ta(V) ligand-to-metal charge transfer (LMCT) transitions. In the reflectance and excitation spectrum the longest-wavelength LMCT band appears at lambda (max) similar to 415 nm. The emission of Ta(NMe2)(5) which originates from the lowest-energy LMCT triplet occurs at lambda (max) = 578 nm and decays with tau = 0.9 mus at r.t. (C) 2001 Elsevier Science B.V.
