The aforementioned methods measure the ensemble-averaged two-point time-correlation function 〈A(0),A(t)〉, withtbeing time andAbeing the dipole moment vector in THz spectroscopy, the polarizability tensor elements in Raman spectroscopy and the particle density in neutron scattering. More recently, ...
Full Spectrum Raman Spectroscopy Setup. Arrows show the intended path of light. White supercontinuum (SC) light is filtered (CF, ExF) and angularly color separated by a transmission grating (ExG, top beamline).The light is then focused by a microscope objective lens (ExL) into a color grade...
Surface-enhanced Raman spectroscopy, on the other hand, combines the high sensitivity (down to a single molecule detection) and the chemical specificity, and can thus function as a suitable technique to quantify and monitor reaction kinetics [4]. In principle, roughened metal nanostructures, ...

Figure 5. A schematic of the experimental set-up of a typical Raman spectrometer and schematic showing applicability of RS to different aspects of algae. In addition, the bioactive components of many microalgae species have been studied using this Raman method. Micro-Raman spectroscopy is the mos...
The aim of this work is a systematical investigation of the polarisation and temperature effects in a diphenylalanine single microtube by Raman spectroscopy. 2. Materials and Methods The solvent 1,1,1,3,3,3-hexafluoro-2-propanol (HFP) was purchased from Sigma-Aldrich and the lyophilized form ...

Spectral data were subjected to partial least squares discriminant analysis, a machine-learning model. We also used Raman spectroscopy and the same analytical procedures to compare and evaluate feces of the horn fly Haematobia irritans after it fed on cattle. Results Five genera and one sub-genus...
Raman spectroscopy is one of the most informative probes for studies of material properties under extreme conditions of high pressure. The Raman techniques have become more versatile over the last decades as a new generation of optical filters and multic
