X-ray techniques. Previous Raman studies have only been performed at ambient pressure and a conclusive assignment of Raman modes is still incomplete,23,35–37 In this letter, we . The application of a multiple-pass gas cell to quasi-cw stimulated Raman scattering is demonstrated to be a powerful method for significantly increasing the sensitivity. As a .

Raman spectroscopy on gases does face challenges, most notably the low sensitivity, which is exacerbated when applied to gases due to their low molecule density. It has been shown that File Size: KB. The present invention relates to systems of methods of measuring selected analytes in blood and tissue using Raman spectroscopy to aid in diagnosis. More particularly, Raman spectra are Cited by:

Get this from a library. Raman spectroscopy of gases at high pressures. [Boris Peter Stoicheff]. 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. Raman spectroscopy is one of the most informative probes for studies of material properties under extreme conditions of high pressure.
