A Raman study of the systems Fe 3− x Cr x O 4 and Fe 2− x Cr x O 3 ☆doi:10.1016/0022-4596(89)90245-4Raman spectra off the solid solutions Fe3−xCrxO4 (0 ≤ x ≤ 2) and Fe2−xCrxO3 (0 ≤ x ≤ 2) have been obtained. The fundamental, overtone, and combination...
In the spectra of the heated sample a band at 657 cm 1 is of particular interest, as it is much more intense than in natural hematite; the possibility that it could be assigned as a magnetite band was discarded. At higher temperatures (900–1000 °C) the disordered structure is perfect...
High-quality Raman spectra of silicate glasses, supercooled liquids and liquids have been obtained in situ to temperatures of 1475°C. The success of the s... Bjorn,O.,Mysen,... - 《Chemical Geology》 被引量: 262发表: 1992年 Effect of K2O on structure–property relationships and phase tra...
Surface-Assisted Photoinduced Reduction of p-Nitrothiophenol Self-Assembled Monolayer Adsorbed on a Smooth Silver Electrode It was observed that surface-enhanced Raman scattering (SERS) spectra of p -nitrothiophenol (PNTP) self-assembled monolayer adsorbed on a smooth silver ele...

Surface-enhanced Raman spectroscopy (SERS) is a highly sensitive spectroscopic technique that provides non-destructive detection at the single-molecule level. Shell-isolated nanoparticle-enhanced Raman spectroscopy (SHINERS) provided a solution to the long-standing limitation of poor universality of tradition...
