Note that fluorescence will be self-quenched at such a short distance, whereas Raman does not suffer from any quenching effect. Such a dense packing is likely a result of strong intermolecular interactions between Raman probes and the polymer matrix. This makes sense chemically because both the ...
Raman spectroscopy and microscopy: a means of imaging material based on the Raman effect, in which a certain number of photons directed at a surface are reflected inelastically, that is, a loss of energy is recorded, generally as a function of the molecular bond length and vibration status....
SummaryTip-enhanced Raman scattering is used to investigate the surface structure of the cell wall of Staphylococcus epidermidis with high lateral resolution and chemical specificity. For most biological samples, the transmission tip-enhanced Raman scattering set-up is ideally suited because it allows the...
Observation of the Auger Resonant Raman Effect 喜欢 0 阅读量: 18 作者:GS Brown,MH Chen,B Crasemann,GE Ice 摘要: Monochromatized synchrotron radiation near the photoionization threshold was used to produce the 2p3/2-1 vacancy state in atomic Xe. Deexcitation of the state through L3-M4M5(...
Raman spectroscopy is increasingly being used in biology, forensics, diagnostics, pharmaceutics and food science applications. This growth is triggered not only by improvements in the computational and experimental setups but also by the development of chemometric techniques. Chemometric techniques are the...
Raman spectroscopy is an optical technique that detects intrinsic vibrational, rotational and other low-frequency modes in molecules upon inelastic scattering of monochromatic light. Because different chemical functional groups scatter light at different frequencies, Raman spectroscopy can be used as a tool...
97 The enhancement of the Raman effect is highly dependent on structures of SERS substrates where metal colloids and their aggregates are most commonly used, although gold and silver nanoparticles are also used.98,99,100 In 2007, Kahraman and colleagues showed that it was possible to employ ...
Raman spectroscopy is an increasingly popular technique in many areas, including biology and medicine. It is based on Raman scattering, a phenomenon in which incident photons lose or gain energy via interactions with vibrating molecules in a sample. These energy shifts can be used to obtain informa...
Observation of SERS effect in Raman optical activity, a new tool for chiral vibrational spectroscopy A new tool for chiral vibrational spectroscopy is reported here. A surface enhanced effect was observed using Raman optical activity (ROA). This observatio... S Abdali - 《Journal of Raman Spectro...
