DFT/TDDFT Investigation on the Electronic Structure and Spectroscopic Properties of Cis-Dioxomolybdenum (VI) Complexes

In this contribution, two mononuclear molybdenum complexes with H2L tridentate (ONO) Schiff base ligand are characterized using computational techniques.Density functional theory (DFT) and its 15-fc0093dx time extension (TD-DFT) calculations are performed to study the electronic structure in ground and excited state and to interpret the electronic absorption spectra in gas and aqueous phases.TDDFT calculations affirm that the LMCT charge transfer dominates for both complexes and a hypochromic effect on absorption properties is observed according to solvent substitution.

All theoretical results compare nicely with sweers island for sale available experimental data.
