Download or read book Isotope Separation by Photoselective Dissociative Electron Capture written by and published by . This book was released on 1978 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A method of separating isotopes based on photoselective electron capture dissociation of molecules having an electron capture cross section dependence on the vibrational state of the molecule. A molecular isotope source material is irradiated to selectively excite those molecules containing a desired isotope to a predetermined vibrational state having associated therewith an electron capture energy region substantially non-overlapping with the electron capture energy ranges associated with the lowest vibration states of the molecules. The isotope source is also subjected to electrons having an energy corresponding to the non-overlapping electron capture region whereby the selectively excited molecules preferentially capture electrons and dissociate into negative ions and neutrals. The desired isotope may be in the negative ion product or in the neutral product depending upon the mechanism of dissociation of the particular isotope source used. The dissociation product enriched in the desired isotope is then separated from the reaction system by conventional means. Specifically, .sup. 235 UF.sub. 6 is separated from a UF.sub. 6 mixture by selective excitation followed by dissociative electron capture into .sup. 235 UF.sub. 5 - and F.

Available in PDF, EPUB and Kindle. Book excerpt: A description of work performed on isotopically selective, photo-enhanced production of SF−5 from SF6 is included. The primary task under the present contract was the construction of a second-generation experimental apparatus for the study of the simultaneous interaction of electrons, photons, and molecules. The collinear electron and laser beam arrangement employed previously has been retained, but a new electron gun design has been adopted which avoids the troublesome interaction of the laser beam with the electron gun filament. The system has been designed for maximum compatibility with aggressive gases such as UF6. Details of the design and construction of this system are given. Proposals for future work include work on SF6 and UF6.

Download or read book Molecular Reaction Dynamics written by Raphael D. Levine and published by Cambridge University Press. This book was released on 2009-06-04 with total page 574 pages. Available in PDF, EPUB and Kindle. Book excerpt: Molecular reaction dynamics is the study of chemical and physical transformations of matter at the molecular level. The understanding of how chemical reactions occur and how to control them is fundamental to chemists and interdisciplinary areas such as materials and nanoscience, rational drug design, environmental and astrochemistry. This book provides a thorough foundation to this area. The first half is introductory, detailing experimental techniques for initiating and probing reaction dynamics and the essential insights that have been gained. The second part explores key areas including photoselective chemistry, stereochemistry, chemical reactions in real time and chemical reaction dynamics in solutions and interfaces. Typical of the new challenges are molecular machines, enzyme action and molecular control. With problem sets included, this book is suitable for advanced undergraduate and graduate students, as well as being supplementary to chemical kinetics, physical chemistry, biophysics and materials science courses, and as a primer for practising scientists.

Download or read book EMR ESR EPR Spectroscopy for Characterization of Nanomaterials written by Ashutosh Kumar Shukla and published by Springer. This book was released on 2016-11-09 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: The subject matter of this book is the application of EMR/ESR/EPR spectroscopy for characterization of nanomaterials. Initial chapters deal with nanomaterials and their classification. Characterization of metallic nanoparticles, metal oxide nanoparticles and rare earth impurity doped nanoparticles from the (ESR) spectrum parameters are covered in the chapters that follow. A special feature of the book is EMR/ESR/EPR spectroscopic characterization of nanoparticles which are important due to their bactericidal and anticancerous properties. Strength of continuous wave (CW) is explained with the help of suitable examples. The book focuses on applications and data interpretation avoiding extensive use of mathematics so that it also caters to the need of young scientists in the life science disciplines. The book includes a comparison with other spectroscopic characterization methods so as to give an integrated approach to the reader. It will prove useful to biomedical scientists and engineers, chemists, and materials engineers in student, researcher, and practitioner positions.
