Abstract: This thesis reports laser spectroscopic studies of gas-phase transition metal dimers using laser ablation/reaction with free jet expansion and laser-induced fluorescence (LIF) spectroscopy technique. Themolecules studied in this work are palladium dimer (Pd2) and vanadium dimer (V2). Many compounds formed from these transition metals are important and functional catalysts in chemical reactions. Therefore, it is of great significance to start from the fundamental level to understand the properties and characteristics of the metal bonding and also the behavior of these metals when reacting with other chemicals. The electronic transitions of Pd2and V2in the visible region were studied. Gas-phase Pd2and V2moleculeswereproduced by laser ablation of palladium and vanadium metal rod, respectively. For the Pd2molecule, eleven vibrational bands were recorded and analyzed, and have been assigned to the 〖[17.1]〗 DEGREES3 □_g□ X DEGREES3 □_u DEGREES+ transition system. The bond length and vibrational frequency of the ground X DEGREES3 □_u DEGREES+ state were determined to be 2.47 A and 211.38 cm-1, respectively. This is the first experimental investigation of the electronic transitions of Pd2.For the V2molecule, six vibrational bands were observed and assigned to a new 〖[19.6] 〗 DEGREES3 □_u DEGREES□□ X DEGREES3 □_g DEGREES□ transition system. Molecular constants for the 〖[19.6] 〗 DEGREES3 □_u DEGREES□ excited state were obtained from high-resolution LIF spectra. The electronic structure of the Pd2andV2molecules was discussed in detail using molecular orbital energy level diagrams, which is important for understanding the nature of chemical bonding in these dimers. Comparison of the transition metal dimers studied in this work with other dimers is also presented. DOI: 10.5353/th_b5089997 Subjects: Transit

This book was released on 1997-07-16 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: The unique properties and applications of transition metal compounds have long fascinated both physicists and chemists. This volume presents theoretical and experimental studies for a deeper understanding of the electronic and vibronic properties of these compounds. In particular, an introduction into properties of spin sublevels of dd*, dÂ*, and ÂÂ* states is given, and a modern ligand field theory based on the Angular Overlap Model is presented. In experimental case studies it is shown how to characterize different types of electronic transitions using modern methods of laser spectroscopy. Consequences of spin-orbit coupling, zero-field splittings, spin-lattice relaxations, chromophore-matrix interactions, Herzberg-Teller/Franck-Condon activities, and localization/delocalization properties are treated.

Available in PDF, EPUB and Kindle. Book excerpt: There exists a large literature on the spectroscopic properties of copper(II) com- 9 pounds. This is due to the simplicity of the d electron configuration, the wide variety of stereochemistries that copper(II) compounds can adopt, and the f- xional geometric behavior that they sometimes exhibit [1]. The electronic and geometric properties of a molecule are inexorably linked and this is especially true with six-coordinate copper(II) compounds which are subject to a Jahn-T- ler effect.However,the spectral-structural correlations that are sometimes d- wn must often be viewed with caution as the information contained in a typical solution UV-Vis absorption spectrum of a copper(II) compound is limited. Meaningful spectral-structural correlations can be obtained in a related series of compounds where detailed spectroscopic data is available. In the fol- 4– lowing sections two such series are examined; the six-coordinate CuF and 6 2+ Cu(H O) ions doped as impurities in single crystal hosts.Using low tempera- 2 6 ture polarized optical spectroscopy and electron paramagnetic resonance, a very detailed picture can be drawn about the geometry of these ions in both their ground and excited electronic states. We then compare the spectrosco- cally determined structural data with that obtained from X-ray diffraction or EXAFS measurements.
