Available in PDF, EPUB and Kindle. Book excerpt: Abstract Anion Photoelectron Spectroscopy of Exotic Species By Terry A. Yen Doctor of Philosophy in Chemistry University of California, Berkeley Professor Daniel M. Neumark, Chair Anion photoelectron spectroscopy is performed on a variety of small, unstable species in both the gas and condensed phases. For the gas-phase studies, the properties of the astrophysically significant molecules C3N- and C5N- and the biologically meaningful deprotonated DNA nucleobases were investigated. Spectra of C3N- and C5N- were obtained at 283 nm using slow electron velocity-map imaging and at 213 nm using field-free time-of-flight, respectively. Adiabatic electron affinities for both species, a term value for the first excited state of C5N, and vibrational frequencies for the degenerate cis and trans bending modes of C3N were determined. Spectra of deprotonated thymine and deprotonated cytosine at 213 nm were obtained to explore their excited state dynamics to understand the photostability of DNA. For the condensed phase studies, a new spectrometer, the liquid microjet apparatus, was assembled and used to measure the vertical binding energy of the solvated electron. A microjet flowing a salt solution intersects a laser at either 266 nm or 213 nm. Two photons from a single nanosecond laser pulse are used to first generate solvated electrons using charge-transfer-to-solvent excitation and to then eject them into vacuum, where they are detected using field-free time-of-flight.

Book excerpt: This thesis describes a combined experimental and theoretical approach towards anion spectroscopy. Motivated by the rich chemistry occurring in the Earth's atmosphere, the first part of thesis describes the design, construction and implementation of an improved anion photoelectron spectrometer based on the velocity map imaging (VMI) principle. This instrument was attached to an existing time-offlight mass spectrometer and conventional anion photoelectron spectrometer. When coupled with a tunable laser, the new spectrometer will allow for high-resolution studies similar to the slow-electron velocity map imaging (SEVI) experiments described by Neumark and co-workers. The spectrometer has been constructed, and preliminary tests have been undertaken. Complementary to the instrument development, a theoretical methodology for the prediction of electron affinities and photoelectron spectra based on the W3-F12 protocol published by Karton and Martin was established. The methodology is applied to methanal-oxide, cis-ethanal-oxide and trans-ethanaloxide yielding electron affinities of 0.57 eV, 0.18 eV and 0.34 eV, respectively. For all of these molecules as well as their anions, total atomisation energies, harmonic frequencies and heats of formation (at 0 K and 298 K) were calculated alongside. Finally, a relatively inexpensive computational analysis of the anharmonic frequencies and intensities for methanal-oxide resulting from vibrational second-order perturbation theory (VPT2) CCSD(T) calculations with different basis sets were compared against experimental IR data as well as high-level vibrational configuration interaction (VCI) calculations. Surprisingly, the VPT2 calculations are on a par with computationally more expensive vibrational configuration interaction (VCI) calculations and hence the first simulation of a high-level IR spectrum of cis-ethanal-oxide is presented.

This book was released on 2019-08-02 with total page 395 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes advanced research on the structures and photochemical properties of polyatomic molecules and molecular clusters having various functionalities under cold gas-phase conditions. Target molecules are crown ethers, polypeptides, large size protonated clusters, metal clusters, and other complex polyatomic molecules of special interest. A variety of advanced frequency and time-domain laser spectroscopic methods are applied. The book begins with the principle of an experimental setup for cold gas-phase molecules and various laser spectroscopic methods, followed by chapters on investigation of specific molecular systems. Through a molecular-level approach and analysis by quantum chemical calculation, it is possible to learn how atomic and molecular-level interactions (van der Waals, hydrogen-bonding, and others) control the specific properties of molecules and clusters. Those properties include molecular recognition, induced fitting, chirality, proton and hydrogen transfer, isomerization, and catalytic reaction. The information will be applicable to the design of new types of functional molecules and nanoparticles in the broad area that includes applied chemistry, drug delivery systems, and catalysts.

Available in PDF, EPUB and Kindle. Book excerpt: Owing to the advances of vacuum ultraviolet and ultrafast lasers and third generation synchrotron sources, the research on photoionization, photoelectrons, and photodetachment has gained much vitality in recent years. These new light sources, together with ingenious experimental techniques, such as the coincidence imaging, molecular beam, pulsed field ionization photoelectron, mass-analyzed threshold ion, and pulsed field ion pair schemes, have allowed spectroscopic, dynamic, and energetic studies of gaseous species to a new level of detail and accuracy. Profitable applications of these methods to liquids are emerging.This invaluable two-volume review consists of twenty-two chapters, focusing on recent developments in photoionization and photodetachment studies of atoms; molecules, transient species, clusters, and liquids.

Download or read book Frontiers of Nano Optoelectronic Systems written by Lorenzo Pavesi and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since their discovery, low dimensional materials have never stopped to intrigue scientists, whether they are physicists, chemists, or biochemists. Investigations of their nature and functions have always been and still are numerous and as soon as a solution is found for a given question, another one is raised. The coupling of nano-materials with photonics, i. e. nano-photonics, has produced a boiling pot of idea, problems, discovery and applications. This statement is abundantly illustrated in the present book. The interest in nano-optoelectronic materials and systems is very widespread, what gives a really international and multicultural flavour to nano-optoelectronic meetings. One of them was organized by our-self in May 2000 in Kiev as a NATO Advanced Research Workshop and EC-Spring School. The arrival of the new millennium provides an obvious transition point at which many aspects of nano-science and nano-engineering of nano photonic systems can be assessed with respect to the research progresses made in the pre ceding decades and to the challenges that lie ahead in the coming decades. This book was planed to mark this with the objective of presenting a collection of papers from experts, which provide broad perspectives on the state-of-the-art in the various disciplines of nano science and nano-engineering and on the directions for future research.
