A review of high-resolution Raman spectroscopy of gases, including spontaneous, incoherent Raman spectroscopy, as well as of nonlinear techniques for coherent anti-Stokes scattering (CARS Author: Alfons Weber. High resolution, quasi-cw, stimulated Raman-gain spectroscopy has become a standard technique for the study of molecular energy levels. This chapter presents that technique for the study of two diverse problems: (1) a determination of the ac Stark effect for the vibration levels of H2 and (2) a demonstration of the first high resolution stimulated Brillion gain spectra in glasses and hemendepo.com: William K. Bischel, Mark J. Dyer, Gregory W. Faris, A. Peet Hickman, Leonard E. Jusinski. For small molecules with an established geometry the technique of high-resolution Raman spectroscopy of low-pressure gases and vapors has furnished a substantial amount of empirical data giving quantitative knowledge about the moments of inertia of these hemendepo.com by: Raman spectroscopy also has a wide usage for studying biominerals. Lastly, Raman gas analyzers have many practical applications, including real-time monitoring of anesthetic and respiratory gas mixtures during surgery. Raman spectroscopy is an efficient and non-destructive way to investigate works of art.
This book deals with basic investigations of the Raman scattering of light by gases, with some attention also being given to liquid substances. After a brief in troductory chapter that delineates the historical development of Raman spectroscopy of gases, high-resolution rotation-vibrational and pure rotational Raman spectros copy is. An instrument is described for recording vibrational–rotational Raman spectra of gases with a resolution of – cm−1. The Raman scattered light is collected by near forward scattering Author: Alfons Weber. Several techniques of exciting Raman spectra of low-pressure gases and vapors with cw laser radiation are described. Both the He–Ne laser with output at å and the Ar+ ion laser with output at and å have been used. The use of the He–Ne laser with a multiple-pass Raman tube inside the laser cavity yields Raman spectra which can be photographed in exposure times that are. The Paperback of the Raman Spectroscopy of Gases and Liquids by A. Weber at Barnes & Noble. After a brief in troductory chapter that delineates the historical development of Raman spectroscopy of gases, high-resolution rotation-vibrational and pure rotational Raman spectros copy is described in Chapters 2 and 3. This book gives a.
JOURNAL OF MOLECULAR SPECTROSCOPY 10, () High-Resolution Raman Spectroscopy of Gases Part XVI. The v3 Raman Band of Methane J. HERRANZ* AND B. P. STOICIIEFF Division of Pure Physics, National Research Council, Ottawa, Canada The rotational structure of the v3 Raman band of CH, has been investigated at high hemendepo.com by: Abstract - Recent results on high-resolution nonlinear rotation-vibrational Raman spectra of gases are described. INTRODUCTION In the last 10 years the resolution in rotation-vibrational Raman spectroscopy of gases has been increased by about two orders of magnitude through the application of the nonlinear techniques which are based on the. Raman spectra can be acquired from nearly all samples which contain true molecular bonding. This means that solids, powders, slurries, liquids, gels and gases can be analysed using Raman spectroscopy. However, in general metals and alloys cannot be analysed using Raman. The use of high-power, narrow-band lasers has significantly improved the resolving power and sensitivity of inverse Raman spectroscopy of gases. In this paper we shall describe this technique, illustrate its capabilities by showing some Q-branch spectra of heavy spherical tops, and survey some.
