raman spectroscopy instrumentation ppt

Raman spectroscopy is a molecular spectroscopic technique that utilizes the interaction of light with matter to gain insight into a material's make up or characteristics, like FTIR. Caumon, F. Rull, S. Sharma EMU-CNRS International School: Applications of Raman Spectroscopy to Earth Sciences and cultural Heritage : 14-16 th of june 2012 Pre Lab Spectroscopy PPT. Thus, 3. Boasting an impressive range of designs, they will support your presentations with inspiring background photos or videos that support your themes, set the right mood, enhance your credibility and inspire your audiences. For instance, this technique is nondestructive and needs little or sample preparation. Raman spectra tend to be less cluttered with, As a consequence, peak overlap in mixtures is, In addition, Raman sampling devices are not, Despite these advantages, Raman spectroscopy has, This lack of use has been due largely to the, Resonance Raman scattering refers to a phenomenon, Under this circumstance, the magnitudes of Raman, As a consequence, resonance Raman spectra have, The most important application of resonance Raman, As an example, the technique has been used to, In these molecules, the resonance Raman bands are, Surface-Enhanced Raman Spectroscopy (SERS), Surface enhanced Raman spectroscopy involves, For reasons that are not fully understood, the, When surface enhancement is combined with the, Not extremely well understood. Material characterization Pharmaceutical analysis Or use it to find and download high-quality how-to PowerPoint ppt presentations with illustrated or animated slides that will teach you how to do something new, also for free. Raman spectroscopy is commonly used in chemistry to provide a fingerprint by which molecules can be identified. - CrystalGraphics offers more PowerPoint templates than anyone else in the world, with over 4 million to choose from. Raman Instrumentation - Duration: 11:02. Share yours for free! To view this presentation, you'll need to allow Flash. Since these early days, Raman instrumentation has evolved markedly. Gases use gas cell 19 Liquids and solids can be sealed in a glass capillary If the compound is colored, it can absorb the laser, get hot and decompose. The experimental problems of Raman spectroscopy are the low intensity of the inelastic scattering and the much larger intensity of the Rayleigh scattering. Raman spectroscopy: Basic principles and applications • Basic principles - Resonance Raman scattering - Surface Enhanced Raman Scattering (SERS) • Instrumentation -Spectrometer - Excitation sources • Raman in catalysis - In situ cells - In situ Raman (of working catalysts) C.V. Raman (1928) Raman Scattering 5 4. Sampling techniques for Raman spectroscopy If the sample is colourless, it does not absorb a visible laser Raman spectroscopy is applicable to solids, liquids or gases. Raman Instrumentation. A Raman microscope couples a Raman spectrometer to a standard optical microscope, allowing high magnification visualization of a sample and Raman analysis with a microscopic laser spot.
