Book Description
This work covers principles of Raman theory, analysis, instrumentation, and measurement, specifying up-to-the-minute benefits of Raman spectroscopy in a variety of industrial and academic fields, and how to cultivate growth in new disciplines. It contains case studies that illustrate current techniques in data extraction and analysis, as well as over 500 drawings and photographs that clarify and reinforce critical text material. The authors discuss Raman spectra of gases; Raman spectroscopy applied to crystals, applications to gemology, in vivo Raman spectroscopy, applications in forensic science, and collectivity of vibrational modes, among many other topics.
Rugged Fiber Optic Probes and Sampling Systems for Remote Chemical Analysis Via the Raman Technique

Book Description
Recent advances in fiber optics, diode lasers, CCD detectors, dielectric and holographic optical filters, grating spectrometers, and chemometric data analysis have greatly simplified Raman spectroscopy. In order to make a rugged fiber optic Raman probe for solids/slurries like these at Savannah River, we have designed a probe that eliminates as many optical elements and surfaces as possible. The diffuse reflectance probe tip is modified for Raman scattering by installing thin dielectric in-line filters. Effects of each filter are shown for the NaNO3 Raman spectrum. By using a diode laser excitation at 780 nm, fluorescence is greatly reduced, and excellent spectra may be obtained from organic solids. At SRS, fiber optic Raman probes are being developed for in situ chemical mapping of radioactive waste storage tanks. Radiation darkening of silica fiber optics is negligible beyond 700 nm. Corrosion resistance is being evaluated. Analysis of process gas (off-gas from SRS processes) is investigated in some detail: hydrogen in nitrogen with NO2 interference. Other applications and the advantages of the method are pointed out briefly.

Use of a Fiber Optic Probe for the Detection and Identification of Explosive Materials by Raman Spectroscopy
Author: IP. HaywardPublisher:
ISBN:
Category : Explosive
Languages : en
Pages : 2
Book Description
A fiber optic probe has been developed that allows Raman spectra to be acquired remotely from a spectrometer. This system has been used to acquire spectra from explosive materials. In this study we demonstrate that it is sufficiently sensitive to rapidly detect traces of PETN in fingerprints of Semtex-Hexplosive. Further development of similar systems will enable the detection and non-destructive identification of contraband materials in the field.

Languages : en
Pages : 451
Book Description
Minimaler Aufwand bei der Probenvorbereitung, hoher Informationsgehalt des Spektrums und die Möglichkeit, mit festen Proben zu arbeiten, machen die Raman-Spektroskopie zunehmend attraktiv. Wie man diese Methode mit modernster Ausrüstung effizient anwendet, zeigt Ihnen das vorliegende Buch. Im Mittelpunkt stehen neue Entwicklungen wie CCDs, Diodenlaser und Fourier-Transform-Techniken. Behandelt werden auch quantitative Analysen, die in der bisher vorhandenen Literatur häufig zu kurz kamen. (08/00)
