Available in PDF, EPUB and Kindle. Book excerpt: Organometallic Photochemistry explores the photochemical properties of transition-metal organometallic complexes, such as metal carbonyls, olefin complexes, arene complexes, and cyclopentadienyl complexes. Isocyanide complexes, hydride complexes, and alkyl complexes are also covered. This book consists of eight chapters and begins with an overview of organometallic complexes and their electronic structure, along with the principles of photochemistry. The chapters that follow are detailed reviews of photochemical studies organized according to type of organometallic. Each chapter is organized according to the central metal atom and its group in the periodic table. The chapter on metal carbonyl complexes focuses on the excited-state chemistry of compounds, such as vanadium, niobium, chromium, molybdenum, manganese, iron, cobalt, and nickel. The next chapter deals with olefin complexes, such as niobium, chromium, rhenium, rhodium, platinum, and copper. The chapters on arene, cyclopentadienyl, isocyanide, hydride, and alkyl complexes explore topics ranging from bonding and electronic structure to photoreactions, photosubstitution, redox chemistry, homolysis, and decomposition. This text is a valuable resource for photochemists and those who are interested in organometallic photochemistry.

This book was released on 2014 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ultrafast time-resolved infrared spectroscopy provides a powerful tool for studying the photochemistry of organometallic complexes. The studies described herein focus on the mechanisms of photochemically initiated organometallic reactions with a particular emphasis on two topics: the role of spin states and spin state changes in organometallic reactions, and the primary photochemical dynamics of complexes containing metal-metal bonds (e.g. transition metal dimers and clusters). Many of these studies seek to uncover trends in reactivity based on the spin states of organometallic reaction intermediates, with the goal of being able to offer some level of predictive insight into the reactivity of complexes as classified by their spin multiplicity. The reactivity of various coordinatively unsaturated reaction intermediates are studied with respect to bond activation, electron transfer, excited state photoisomerization, and other classes of reactions important to organometallic catalysis. A second focus, which shares some degree of overlap with the topic of spin state changes, is the primary photochemistry of complexes containing metal-metal bonds. Several of the studies reported herein use time-resolved infrared spectroscopy to examine the primary photochemical processes occurring upon excitation of transition metal dimers and clusters, and often spin state changes also found to play an important role. Results of computational chemistry calculations are frequently used to facilitate interpretation of the experimental results by computation of structures, relative energies, infrared spectra, and spin-orbit coupling for the complexes studied experimentally. Additional studies outside these two primary areas of focus also investigated the ring-slippage of cyclopentadienyl ligands and the CO-delivery properties of a popular CO-Releasing Molecule.

Download or read book Photosensitization and Photocatalysis Using Inorganic and Organometallic Compounds written by K. Kalyanasundaram and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 475 pages. Available in PDF, EPUB and Kindle. Book excerpt: Photosensitization and photocatalysis refer to processes by which permanent chemical transformations are induced on substrates (organic/inorganic) by radiation to which the substrates themselves are transparent. Such transformations can be highly specific, very efficient, and occur under mild conditions. Herein lies the power of photochemical methods for possible applications in the field of conversion and storage of solar energy. This book provides a recent survey of the progress in this important area in catalysis, with an emphasis on inorganic complexes and organometallic compounds as the key light aborbers. The book is organized in three parts: fundamentals, followed by applications. Discussions cover a wide variety of photosensitized or photocatalyzed reactions: decomposition of water, reduction of CO2 and CO; spectral sensitization in photoelectrochemical cells; transformations (oxidation, reduction, isomerization, hydrogenation, dehydrogenation, carbonylation, etc.) of organics such as alkanes, alkenes, alcohols, etc. In view of the variety of systems (sensitizers, substrates) and the topics covered, the volume is unique in the field of photochemistry and will appeal to academic and industrial researchers in various subdisciplines of chemistry, material science and catalysis.

This book was released on 2019 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work aims at deeper understanding of chemical reaction dynamics, ultrafast photochemical and photophysical relaxation pathways, and energy redistribution and dissipation in the liquid phase on a femto-to-picosecond timescale. Breaking and making of chemical bonds, structural reorganization, and energy flow are all the essence of chemistry, and all occur on the time scale of molecular vibrations (tens of femtoseconds). Important insights about the structure of evolving molecules, relaxation phenomena, and ultrafast photochemical and photophysical population dynamics can be obtained using sub-50-fs time-resolved transient absorption spectroscopy. As a result, highly viable and/or unique information about the mechanism of relaxation dynamics and the nature of short-lived intermediates can be gained. Furthermore, ultrashort laser pulses with duration of 100 fs or shorter can help set up and detect coherent motion in vibronic excited and ground states. Coherence observed in product states provides the knowledge about electronic and nuclear motion along the relaxation path. This yields the information about the potential energy surfaces involved in the photochemical or photophysical process that occurs. The knowledge acquired from such experiments can be used as an entry point for control of femtochemical processes in solution. The technical aspect of this work focuses on developing and optimizing the ultrafast transient absorption setup for studying ultra-rapid photochemical relaxation dynamics in the molecules of interest, namely, geminal dibromocycloalkanes and halogen-containing transition metal complexes. Excitation pulses from deep-UV to near-IR were temporally compressed using prisms compressors to generate sub-40 fs laser pulses. Also, stable white-light continuum pulses used for probing were generated in the wide spectral range of 280 - 760 nm. This thesis is divided into two main parts. The first part provides information about ultrafast dynamics (10-fs time resolution after deconvolution) of geminal dibromocycloalkanes. The second part covers ultrafast radiationless relaxation dynamics of halogen-containing transition metal complexes (IrBr62-, IrCl62-, etc.). A particular focus in this part is on excitation into several vibronic states of the different nature (ligand-to-metal charge-transfer (LMCT) and intraconfigurational), where the lowest-excited intraconfigurational state is accessed via direct femtosecond near-IR (2000 nm) excitation.

This book was released on 1992 with total page 466 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main emphasis in this book is on the photoprocesses of transition metal complexes and biosystems, but not to the exclusion of other photoprocesses. The book will thus be useful to a wide range of researchers. Beginning with a basic introduction to photophysics, quantum chemistry, and the spectroscopic techniques used for the study of organometallic intermediates and biliproteins, the book goes on to discuss the photochemistry of organometallics, special attention being paid to the photochemistry of metalbonded carbonyls and polynuclear systems in supramolecular photochemistry. After moving to a discussion of large systems, the book then developes some aspects of the photophysics of biosystems, before closing with a discussion of artificial photosynthetic model systems.
