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

INTRODUCTION In recent years, the need for a complete collection of information rele vant to diatomic moleeules has become evident. Several excellent collections of this type of information have been available for many years (Refs. 1-3); however, the state of our collective knowledge has been considerably expanded since their publication.

This book was released on 2017-08-02 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over recent years electronic spectroscopy has developed significantly, with key applications in atmospheric chemistry, astrophysics and astrochemistry. High Resolution Electronic Spectroscopy of Small Molecules explores both theoretical and experimental approaches to understanding the electronic spectra of small molecules, and explains how this information translates to practice. Professors Geoffrey Duxbury and Alexander Alijah present the links between spectroscopy and photochemistry, and discuss theoretical treatments of the interaction between different electronic states. They provide a thorough discussion of experimental techniques, and explore practical applications. This book will be an indispensable reference for graduate students and researchers in physics and chemistry working on theoretical and practical aspects of electronic spectra, as well as atmospheric scientists, photochemists, kineticists and professional spectroscopists.
Download or read book Cavity Ring down Spectroscopy of Astrophysically Relevant Molecular Species Toward Quantitative and High Resolution Studies Using Spectro temporal Properties of High Finesse Cavities written by Viet Tiep Phung and published by . This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main objective of this PhD was to develop spectroscopic techniques using high finesse optical cavities. These were applied to the measurement of quantitative spectroscopic data for neutral, radical and ionic molecular species of astrophysical interest in the near infrared and visible spectral range. The first part was devoted to the measurement of the oscillator strength of high vibrational overtone bands of the cyanoacetylene (HC3N) molecule with the Cavity Ring Down Spectroscopy (CRDS) technique. The second part was devoted to the study of the spectroscopy of transient neutral and ionic species. For that, an inductively radio frequency (RF) discharged has been coupled to the CRDS set up. The pertinence of this plasma to efficiently produce anions was demonstrated via the quantitative measurement of the C2 / C2− ratio in a wide variety of conditions. A quantitative spectral analysis of the radical isotopomers 14NH2 and 15NH2 was also performed for the first time. This study provides experimental data that will allow to better constraint the 15N/14N isotopic ratio in comets through the emission lines of these two amino bearing isotopomers. The third and last part of the work was devoted to the development of a CRDS scheme called Broad Band Dual Etalon Frequency Comb Ring Down Spectroscopy. This new heterodyne technique, based on the use of the microsecond frequency combs generated by two high finesse optical cavities, should allow performing molecular spectroscopy with ultrahigh spectral resolution. First proof experiments were performed and perspective's for improvement of the method is provided.
