This book was released on 1996 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: New methods are explored for producing and characterizing proposed new HEDM molecules - covalent nitrogen and oxygen rings. A laser ablation 'supersonic catalytic plasma reactor' was developed, wherein a metal target is vaporized by a pulsed UV laser and reactant gases are added to the buffer gas. A pulsed corona discharge nozzle was developed for the same purpose. Cavity Ringdown and VUV laser ionization mass spectroscopy are Laser Absorption Spectroscopy developed for characterizing the products of the above sources. Initial tests of these sources for producing coinage metal silicides have been carried out. Cavity Ringdown Laser Absorption Spectroscopy has been extended into the infrared region of the spectrum using two different technologies. Studies of water clusters in pulsed supersonic beams and of molecules in flames have been carried out.

Available in PDF, EPUB and Kindle. Book excerpt: Solid-state laser and luminescent materials activated by rare-earth or transition metals ions are widely used for solid-state lasers, luminescent lamps, flat displays, optical fibre communication systems, and other photonic devices. The unique solid-state electronic properties enable the activators in solids to emit photons efficiently in visible and IR regions. The rapid advances in both materials science and optoelectronics, particularly, the development of new methods of material synthesis and device fabrication, have been stimulating the growing interests in the deep insights of spectroscopic properties of solid-state laser and luminescent materials. This book brings together essential and practical knowledge of spectroscopic physics. This includes, atomic spectroscopy, mathematical theory, rare earth ions in materials, light emission and absorption, spectral properties, non-radiative transitions and energy migration.

Download or read book Laser Spectroscopy of Highly Vibrationally Excited Molecules written by Vladilen Stepanovich Letokhov and published by CRC Press. This book was released on 2021-07-29 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: Laser spectroscopy has been perfected over the last fifteen years to become a precise tool for the investigation of highly vibrationally excited molecules. Intense infrared laser radiation permits both the multiple-photon resonant excitation and the dissociation of polyatomic molecules. In this book, the latest results of some of the foremost Soviet researchers are published for the first time in the West. Laser Spectroscopy of Highly Vibrationally Excited Molecules contains a comprehensive study of both the experimental and theoretical aspects of the basic photophysical interactions that occur in these processes. The book first focuses on the nonlinear interaction between the resonant vibrational mode and the intense infrared field and then examines the nonlinear interaction between the vibrational modes themselves due to anharmonicity. These interrelated processes determine all the characteristics of polyatomic molecules in an infrared field. The book also discusses related phenomena such as spectra broadening, optical resonance, photon echoes, and dynamical chaos. It includes examples of multiple-photon resonant excitation such as the excitation of OsO4 by CO^O2 laser radiation, which is detected by the visible luminescence that results. This book will be of great interest to researchers and postgraduate students in infrared laser spectroscopy and the laser chemistry of molecules and applications of isotope separation.
