Raman Spectroscopic Studies of Silicotitanates
The Journal of Physical Chemistry B, 2000Silicotitanates are nanoporous materials that have been used as selective ion exchangers for removing cesium from waste streams and catalysts for promoting oxidation and hydroxylation reactions. The local bonding configurations and network charge distribution are known to influence the selectivity and reactivity of these compounds.

Raman spectroscopic studies of Li2SO4
Solid State Ionics, 1983Abstract The normal mode frequency distribution in Li2SO4 is compared with those of LiNaSO4 and LiKSO4. The temperature dependent bandwidth of a low frequency mode attributed to librational motion of the sulfate ion is measured from room temperature to the phase transition temperature at 573°C.

Raman spectroscopic studies on bacteria
SPIE Proceedings, 2000Routine clinical microbiological identification of pathogenic micro-organisms is largely based on nutritional and biochemical tests. Laboratory results can be presented to a clinician after 2 - 3 days for most clinically relevant micro- organisms. Most of this time is required to obtain pure cultures and enough biomass for the tests to be performed. In

Raman Spectroscopic Studies of Amsacrine
Applied Spectroscopy, 1992Amsacrine (4′-(9-acridinylamino)methanesulfon- m-anisidide) in both solid and aqueous forms was characterized with the use of resonance and nonresonance Raman spectroscopy (including FT-Raman spectroscopy). Evidence that the acridine nucleus is the dominant chromophoric unit contributing to the resonance Raman spectrum is based upon the apparent ...

Raman spectroscopic studies of silk
Journal of Raman Spectroscopy, 1995AbstractThe Fourier transform Raman spectra of silk at several stages of its processing from raw natural and cultivated cocoons to woven fabric were obtained. The application of near‐infrared excitation to the recording of quality Raman spectra from bulk samples, including Russian and Chinese varieties, and from a single 10 μm fibre is demonstrated ...

Raman Spectroscopic Characterization of Graphene
Applied Spectroscopy Reviews, 2010Abstract The recent progress using Raman spectroscopy and imaging of graphene is reviewed. The intensity of the G band increases with increased graphene layers, and the shape of 2D band evolves into four peaks of bilayer graphene from a single peak of monolayer graphene.

Infrared and Raman Spectroscopic Imaging
Applied Spectroscopy Reviews, 1994Introduction Microscopies based on the vibrational spectrum of a molecule provide perhaps the closest approach to universally applicable, chemically selective contrast generation techniques. Infrared and Raman microscopic imaging both use the technology of light microscopy, although in modified form.

Raman Spectroscopic Characterisation Of Liver
1997NIR-multichannel Raman microspectroscopy was used to obtain spectra of rat and human liver. Raman spectra of rat liver in situ were obtained by means of a simple Raman fiber optic probe.
