Download and read online ebook Ultrafast Electronic and Structural Dynamics write by Kiyoshi Ueda. This book was released on 2024. Ultrafast Electronic and Structural Dynamics available in PDF, EPUB and Kindle. Zusammenfassung: This book illustrates advanced technologies for imaging electrons and atoms in action in various forms of matter, from atoms and diatoms to protein molecules and condensed matter. The technologies that are described employ ultrafast pulsed lasers, X-ray free electron lasers, and pulsed electron guns, with pulse durations from femtoseconds, suitable to visualize atoms in action, to attoseconds, needed to visualize ballistic electron motion. Advanced theories, indispensable for understanding such ultrafast imaging and spectroscopy data on electrons and atoms in action, are also described. The book consists of three parts. The first part describes probing methods of attosecond electron dynamics in atoms, molecules, liquids, and solids. The second part describes femtosecond structural dynamics and coupling of structural change and electron motion in molecules and solids The last part is dedicated to ultrafast photophysical processes and chemical reactions of protein molecules responsible for biological functions

This book was released on 2020-09-10. Chemistry in Action: Making Molecular Movies with Ultrafast Electron Diffraction and Data Science available in PDF, EPUB and Kindle. The thesis provides the necessary experimental and analytical tools to unambiguously observe the atomically resolved chemical reactions. A great challenge of modern science has been to directly observe atomic motions during structural transitions, and while this was first achieved through a major advance in electron source brightness, the information content was still limited and new methods for image reconstruction using femtosecond electron diffraction methods were needed. One particular challenge lay in reconciling the innumerable possible nuclear configurations with the observation of chemical reaction mechanisms that reproducibly give the same kind of chemistry for large classes of molecules. The author shows that there is a simple solution that occurs during barrier crossing in which the highly anharmonic potential at that point in nuclear rearrangements couples high- and low-frequency vibrational modes to give highly localized nuclear motions, reducing hundreds of potential degrees of freedom to just a few key modes. Specific examples are given in this thesis, including two photoinduced phase transitions in an organic system, a ring closure reaction, and two direct observations of nuclear reorganization driven by spin transitions. The emerging field of structural dynamics promises to change the way we think about the physics of chemistry and this thesis provides tools to make it happen.

Download and read online ebook Femtochemistry and Femtobiology write by Abderrazzak Douhal. This book was released on 2002. Femtochemistry and Femtobiology available in PDF, EPUB and Kindle. This book contains important contributions from top international scientists on the-state-of-the-art of femtochemistry and femtobiology at the beginning of the new millennium. It consists of reviews and papers on ultrafast dynamics in molecular science.The coverage of topics highlights several important features of molecular science from the viewpoint of structure (space domain) and dynamics (time domain). First of all, the book presents the latest developments, such as experimental techniques for understanding ultrafast processes in gas, condensed and complex systems, including biological molecules, surfaces and nanostructures. At the same time it stresses the different ways to control the rates and pathways of reactive events in chemistry and biology. Particular emphasis is given to biological processes as an area where femtodynamics is becoming very useful for resolving the structural dynamics from techniques such as electron diffraction, and X-ray and IR spectroscopy. Finally, the latest developments in quantum control (in both theory and experiment) and the experimental pulse-shaping techniques are described.
