Re and Br X-ray Absorption Near-Edge Structure Study of the Ground and Excited States of [ReBr(CO)3(bpy)] Interpreted by DFT and TDDFT Calculations
Popis výsledku v původním jazyce
X-ray absorption spectra of fac-[ReBr(CO)3(bpy)] near the Re L3- and Br K-edges were measured in a steady-state mode as well as timeresolved at 630 ps after 355 nm laser pulse excitation. Relativistic spinorbit time-dependent density functional theory (TD-DFT) calculations account well for the shape of the near-edge absorption (the "white line") of the ground-state Re spectrum, assigning the lowest-lying transitions as core-toligand metal-to-ligand charge transfer from Re 2p3/2 into predominantly ?*(bpy) molecular orbitals (MOs) containing small 5d contributions, followed in energy by transitions into ?* Re(CO)3 and delocalized ?*/?* MOs. Transitions gain their intensities from Re 5d and 6s participation in the target orbitals. The 5d character is distributed over many unoccupied MOs; the 5d contribution to any single empty MO does not exceed 29%. The Br K-edge spectrum is dominated by the ionization edge and multiple scattering features, the pre-edge electronic transitions being very
