Excited states and emission spectroscopy of organometallic compounds interpreted by time-dependent theory
نویسندگان
چکیده
Luminescence spectra of organometallic molecules in crystals or glasses are discussed and interpreted by using the time-dependent Ž . theory of electronic spectroscopy. Emphasis is placed on determining bond length and bond angle changes excited-state distortions between the ground and excited electronic states. The physical meaning of the dynamic processes and the molecular properties are described and illustrated with both theoretical calculations and experimental spectra. The discussion begins with spectra involving only Ž one displaced normal mode, and continues with the effects of multiple normal modes. Both common features and unusual effects the . ‘Beat’ and the ‘MIME’ are described and interpreted. Finally, the effects of normal mode coupling and of electronic state coupling are briefly described. q 1998 Elsevier Science S.A.

متن کاملSimulating Valence-to-Core X-ray Emission Spectroscopy of Transition Metal Complexes with Time-Dependent Density Functional Theory.
Valence-to-core (VtC) X-ray emission spectroscopy (XES) has emerged as a powerful technique for the structural characterization of complex organometallic compounds in realistic environments. Since the spectrum represents electronic transitions from the ligand molecular orbitals to the core holes of the metal centers, the approach is more chemically sensitive to the metal-ligand bonding characte...

In order to reach a fundamental understanding of interactions between electromagnetic radiation and molecular materials, experimental measurements need to be supplemented with theoretical models and simulations. With the use of this combination, it is possible to characterize materials in terms of, e.g., chemical composition and molecular structure, as well as achieve time-resolution in studies...

The dangling carboxylic acid moiety of the known platinum(II) complex, [Pt(edma)Cl(2)] (edma = ethylenediaminemonoacetic acid), was functionalized via amide coupling chemistry with benzyl amine and dansyl ethylenediamine to afford the derivatives [Pt(edBz)Cl(2)] (1) and [Pt(edDs)Cl(2)] (2). Subsequent oxidation of these platinum(II) complexes with iodobenzene dichloride in DMF yielded the respe...
