Crvo4
WebApr 17, 2024 · The structural stability and physical properties of CrVO4 under compression were studied by X-ray diffraction, Raman spectroscopy, optical absorption, resistivity measurements, and ab initio calculations up to 10 GPa. High-pressure X-ray diffraction and Raman measurements show that CrVO4 undergoes a phase transition from the ambient … WebRaman Shift Calculator. Raman spectroscopy is a form of vibrational spectroscopy technique where vibrational, rotational frequencies and low-frequency modes of a system caused by the inelastic scattering of light (the Raman shift) are monitored. These vibrational frequencies are used as chemical fingerprints for the identification of molecules.

WebJun 1, 2001 · DTA and XRD studies of the Fe 2 V 4 O 13 –Cr 2 V 4 O 13 system have shown that continuous solid solutions of a Fe 2–x Cr x V 4 O 13 type, bearing a Fe 2 V 4 O 13 structure, are formed in the system. With the increasing degree of the Cr3+ ion incorporation into the Fe 2 V 4 O 13 structure, a contraction of the solid solution crystal lattice develops. WebSuch a phase transition (CrVO4-type → wolframite), driven by pressure, also was previously observed in indium vanadate. The crystal structure of both phases and the pressure dependence in unit-cell parameters, Raman-active modes, resistivity, and electronic band gap, are reported.
