Available in PDF, EPUB and Kindle. Book excerpt: The series Topics in Current Chemistry presents critical reviews of the present and future trends in modern chemical research. The scope of coverage is all areas of chemical science including the interfaces with related disciplines such as biology, medicine and materials science. The goal of each thematic volume is to give the non-specialist reader, whether in academia or industry, a comprehensive insight into an area where new research is emerging which is of interest to a larger scientific audience. Each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years are presented using selected examples to illustrate the principles discussed. The coverage is not intended to be an exhaustive summary of the field or include large quantities of data, but should rather be conceptual, concentrating on the methodological thinking that will allow the non-specialist reader to understand the information presented. Contributions also offer an outlook on potential future developments in the field. Review articles for the individual volumes are invited by the volume editors. Readership: research chemists at universities or in industry, graduate students
Download or read book Photosynergetic Responses in Molecules and Molecular Aggregates written by Hiroshi Miyasaka and published by Springer Nature. This book was released on 2020-09-05 with total page 593 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book compiles the accomplishments of the recent research project on photochemistry “Photosynergetics”, supported by the Ministry of Education, Culture, Sports, Science and Technology of Japan, aiming to develop and elucidate new methods and molecules leading to advanced utilization of photo-energies. Topics include photochemical responses induced by multiple excitation, multiphoton absorption, strong modulation of electronic states, developments of new photofunctional molecules, mesoscopic actuations induced by photoexcitation, and novel photoresponses in molecules and molecular assemblies. The authors stress that these approaches based on the synergetic interaction among many photons and many molecules enable the expansion of the accessibility to specific electronic states. As well, they explain how the development of reaction sequences and molecules/molecular assemblies ensure “additivity” and “integration” without loss of the photon energy, leading to new photoresponsive assemblies in meso- and macroscopic scales.
Download or read book Transition Metal and Rare Earth Compounds written by Hartmut Yersin and published by Springer. This book was released on 2003-07-01 with total page 201 pages. 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.

Download or read book Excited States of D6 and D8 Transition Metal Complexes written by Gregory Stephen Huff and published by . This book was released on 2017 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: The electronic excited states of some platinum(II), rhenium(I) and ruthenium(II) complexes with diimine ligands were studied with spectroscopic and computational tools. This type of complex can form charge-transfer (CT) excited states which are potentially useful for solar energy applications. fac-Re(CO)3(N^N)L] complexes are discussed first. The complexes form luminescent CT states where an excited electron is localized on the N^N ligand. Resonance Raman spectroscopy shows how the origin of this excited electron can change from ligand-based to metal-based depending on donating ligand L. Variations in the N^N ligand in Re(I) complexes are also studied. Time-resolved infrared spectroscopy shows how complexes with 2-pyridyl-1,2,3-triazole (pytri) ligands form excited states with a smaller degree of charge separation than is typically seen. [Ru(pytri)(bpy)2]2+ complexes are shown to form CT states which are comparable to those of [Ru(bpy)3]2+ where an excited electron is localized on a bpy ligand. However, the pytri complexes have unusually short excited state lifetimes due to rapid formation of metal-centered triplet states (3 MC) which are characterized using density functional theory (DFT) calculations. A series of square-planar Pt(II) complexes containing pytri ligands with various donor ligands (chloride, phenylacetylide, catechol and benzenedithiol) are examined next. The ligand donor strength can control whether the complex is luminescent by adjusting the relative energies of the 3MC and CT states. Resonantly enhanced Raman bands associated with the pytri ligand are very consistent across the series. The catecholate and dithiolate complexes have an unexpected ordering of their CT absorption bands which is not predicted by DFT calculations. Finally, complexes in which an organic electron donor is appended are discussed. This brings about an additional CT state which adds an additional layer of complexity to the systems studied in previous chapters. The light-harvesting ability of the complexes is increased but their photophysical properties also change drastically.

This book was released on 2012-12-06 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: The scope of this paper is to recall fundamental notions of the molecular spectroscopy and dynamics, necessary for discussion of photophysical and photochemical processes in condensed phases. We will thus treat in a more detailed way the specific features which are important for molecular systems strongly interacting with their environment. Other aspects such as the time evolution of isolated molecules, single-level excitation and state-to-state chemistry, important for the gas-phase photophysics are omitted. We start (Sec.2) with a brief description of radiative processes (light absorption and emission) in molecules. In the quantum-mechanical treatment of this problem, the appropriate basis is that of so-called zero-order states, corresponding to the traditional scheme of electronic states (singlets, doublets, triplets etc.) and vibrational levels belonging to each state. The important point will be deduction of selection rules for most radiative transitions. At this stage all molecular states are considered as stationary states. In order to treat the breakdown of simple selection rules and non-radiative transitions between individual molecular states, it is necessary to take into account the mechanisms coupling the zero-order states (Sec.3). We will first focus on intramolecular coupling effects and then discuss the solvent effects on intramolecular relaxation processes. The problem of the non-radiative transfer of the electronic energy between different molecules - closely related to that of the energy dissipation within a single molecule will be treated in Sec.4.
