We also report oriented Raman spectrum of garnets, in particular almandine. Almandine is generally cubic, so there should be little change in Raman intensities as a function of orientation. This is observed for a sample of almandine from Ontario, Canada; but not for a sample of almandine from...

Currently, μ-Raman spectroscopy is intensively used to measure stresses in silicon wafers, structures, and devices of known crystallographic orientations. For these cases, the determination of stresses from Raman peak shifts is straightforward. In multicrystalline silicon, however, arbitrary grain ...
Raman spectroscopy of the CH stretching modes was used to investigate the molecular level response of hexahydro‐1,3,5‐trinitro‐s‐triazine (RDX) to shock compression. Single crystals of [111], [210], and [100] orientation were compressed under stepwise shock loading to peak stresses from 3....
(4) and (10). This contrasts with other vibrational techniques such as infrared or Raman spectroscopies, which provide only 〈P2〉 or 〈P2〉 and 〈P4〉 momenta32,33, respectively, thus limiting the number of Legendre polynomials to the fourth rank order in Eq. (5). In an effort to ...
Using polarized Raman spectroscopy, we have recorded Raman spectra from individual electrospun Nylon-6 nanofibers. Analysis of these single-fiber spectra, compared to those of unoriented and oriented Nylon-6 films, indicates significant molecular orientation. Because electrospinning produces fibers in a ...
We demonstrate this on the microscopic scale by polarized micro-Raman spectroscopy of the illuminated zone. The reorienta-tion process was followed in time as a function of incident light power and at different temperatures in the neighborhood of T g, by monitoring the induced birefringence. Thus...
We report direct measurements of local grain orientation and residual strain in polycrystalline, C-axis oriented thin YBa[sub 2]Cu[sub 3]O[sub 7-δ] superconducting films using polarized Raman spectroscopy. Strain dependence of the A[sub g] Raman active mode at 335 cm-1 was calibrated and ...
Polarised Raman spectroscopy is a vibrational spectroscopic technique that is used widely for the chemical and physical analyses of materials since it is both non-destructive and suitable for remote analysis. In particularly over the last 40 years, the technique has been developed and applied for the...
