spectrum clean-upquantificationSolutions of N2O4 and N2O5 in anhydrous and aqueous nitric acid were examined by Raman spectroscopy to gain a more detailed knowledge of the species present in these solutions and to assess the applicability of Raman spectroscopy as an analytical measurement techniqu...
The spectrum obtained after 6 hours exposure was rich in Raman lines. Raman displacements of 424, 549, 730, 915, 1043, 1181 and 1378 cm.1 were obtained. These clearly arise from the sulphuric acid and are in good agreement with previously recorded values. In addition, a number of other ...
- 《Journal of Raman Spectroscopy》 被引量: 176发表: 1997年 INTENSITY IN THE RAMAN EFFECT: V. THE EFFECT OF INTERMOLECULAR INTERACTION ON THE RAMAN SPECTRUM OF CARBON DISULPHIDE The Raman spectrum of CS2 has been obtained photoelectrically for the liquid and solutions of varying concentrations in...
Miller indices with black and purple colors indicate the crystallographic γ-Fe2O3 and anatase TiO2 phases, respectively, (b) TG curve, and (c) UV vis spectrum of the ternary nanocomposite. Using the modified Scherrer approach, the anisotropic size broadening can be written as a linear ...
In this way, intercalation of adriamycin by DNA was studied using different excitation lines to probe either the DNA Raman spectrum (364 nm) or the RR spectrum of the bound drug (457 nm). Show moreView chapterExplore book Globins and Other Nitric Oxide-Reactive Proteins, Part B Changyuan ...
of theemission spectrum. The beam coming from the SR source is cleaned from the higher order harmonics of the undulator through two mirrors. A first gold-coated GLIDCOP, internally water-cooled, deviates the photons in the vertical plane with an angle of 60 degrees and a second externally ...
charac-terized by infrared (IR) and Raman spectrum, respectively; the morphology was observed by scanning electronic mi-croscope (SEM); the application of carbon nanotubes after acidification was introduced in briefly.Key words:multi-wall carben nanotubes;acidification;infrared spectrum;Raman spectrum ...
Raman spectrum of 10−2 M S.A.M. thiophenol molecules measured from different kinds of SERS substrates (labeled with different colors in the figure). All measurement are conducted under the same laser and surrounding conditions. Full size image Table 2 The average intensity of peak sited ...
It was concluded from the spectra that a pyridine molecule is chemisorbed on the iron surface in 0.1M . A weak SERS spectrum of pyridinium ion adsorbed on iron was observed in 0.25M because of a low adsorbability of the ion on the iron surface in the solution. 展开 ...
11 Raman scattering is induced by monochromatic light directed into the sample where photons interact with the molecules, which then emit photons of the same (Rayleigh), lower (Stokes), and higher energy (anti-Stokes) than the absorbed photons. The Raman spectrum is generated upon detection of ...
