Abstract: Abstract of thesis entitled CAVITY RINGDOWN LASER ABSORPTION SPECTROSCOPY OF FREE RADICALS submitted by MA TONGMEI for the degree of Doctor of Philosophy at The University of Hong Kong in July 2004 This thesis reports studies of the electronic transitions of gas phase diatomic transition metal containing free radicals in the spectral region of 440-520 nm using the technique of laser vaporization/reaction with supersonic free jet expansion (LVRFE) and cavity ringdown laser absorption spectroscopy (CRLAS) with a pulsed Nd: YAG pumped dye laser system. This combination of experimental techniques offered great advantages in versatility of producing metal containing free radicals and sensitivity for their detection. Three different molecular transition systems were recorded and analyzed. They are the (0,0), (1,0) and (2,0) bands of the 2 2 3 3 LΦ - XΔ transition of iridium carbide (IrC); the (0,0) band of the EΔ - X Δ 7/2 5/2 2 + 2 + transition of vanadium nitride (VN); the (2,0) and (2,1) bands of the BΣ - XΣ transition of yttrium oxide (YO), respectively. Least squares fit of measured line positions of these transitions yielded vibrational, rotational and spin fine structure constants for the electronic states studied. Molecular orbital energy level diagrams have been constructed to explain the observed molecular properties in these free radicals. In addition, a setup of cavity enhanced absorption spectroscopy (CEAS) using tunable continuous wave diode laser and an optical cavity with ultra-high reflectivity mirrors was constructed. Data acquisition procedure is modified to extract the highest signal at a specific time period rather than to record the -9 -1 time-integrated signal as usual. An absorption sensitivity of about 4.8 10 cm could be achieved. DOI: 10.5353/th_b3013734 Subjects: Free radicals (Chemistry) Cavity-ringdown spectroscopy Transition metal complexes Laser spectroscopy

This book was released on 1998 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: A high resolution infrared cavity ringdown laser absorption spectrometer has been developed to study proposed HEDM molecules and metal containing clusters. Using a novel tunable pulsed Alexandrite ring laser, we are able to generate tunable visible radiation with ca, 40 MHz bandwidth. This tunable visible light is downconverted to the infrared using stimulated Raman scattering in H2 and D2. With this system, tunable radiation from the UV to the far infrared can be generated with ca, 100 MHz bandwidth. We will test this system using our pulsed supersonic laser vaporization source to study both metal and carbon containing species. Infrared Cavity Ringdown Spectroscopy has also been used to study water clusters in both pulsed supersonic beams and pulsed discharged nozzles.

Available in PDF, EPUB and Kindle. Book excerpt: Using lasers to induce and probe surface processes has the advantages of quantum state specificity, species selectivity, surface sensitivity, fast time-resolution, high frequency resolution, and accessibility to full pressure ranges. These advantages make it highly desirable to use light to induce, control, or monitor surface chemical and physical processes. Recent applications of laser based techniques in studying surface processes have stimulated new developments and enabled the understanding of fundamental problems in energy transfer and reactions. This volume will include discussions on spectroscopic techniques, energy transfer, desorption dynamics, and photochemistry.

This book was released on 2021-07-28 with total page 397 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.

This book was released on 2013-09-03 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: This lecture notes book presents how enhanced structural information of biomolecular ions can be obtained from interaction with photons of specific frequency - laser light. The methods described in the book "Laser photodissociation and spectroscopy of mass-separated biomolecular ions" make use of the fact that the discrete energy and fast time scale of photoexcitation can provide more control in ion activation. This activation is the crucial process producing structure-informative product ions that cannot be generated with more conventional heating methods, such as collisional activation. The book describes how the powerful separation capabilities and sensitivity of mass spectrometry (MS) can be combined with the structural insights from spectroscopy by measuring vibrational and electronic spectra of trapped analytes. The implementation of laser-based photodissociation techniques in MS requires basic knowledge of tunable light sources and ion trapping devices. This book introduces the reader to key concepts and approaches in molecular spectroscopy, and the light sources and ion traps employed in such experiments. The power of the methods is demonstrated by spectroscopic interrogation of a range of important biomolecular systems, including peptides, proteins, and saccharides, with laser light in the ultraviolet-visible, and infrared range. The book "Laser photodissociation and spectroscopy of mass-separated biomolecular ions" is an indispensable resource for students and researchers engaged or interested in this emerging field. It provides the solid background of key concepts and technologies for the measurements, discusses state-of-the-art experiments, and provides an outlook on future developments and applications.
