MnGeO3 single-crystal samples have been synthesized by optical zonal melting and spontaneous crystallization. X-ray crystal analysis showed the first sample to be a two-phase one with phase ratio as follows: 17% – monoclinic C2/c, and 83%– orthorhombic Pbca; the phase ratio of the second sample was unknown. Raman spectra have been produced for these samples. Lattice dynamics has been simulated and polarization dependencies of lines’ intensities have been analyzed to interpret experimental Raman spectra and to attribute lines to the spectra of monoclinic and orthorhombic phases.

Coherent manipulation of the Raman-induced gratings in atomic media
Arkhipkin, V. G.; Myslivets, S. A. (2016-01)We consider dynamically controllable periodic structures (gratings), resulting from Raman interaction of a weak probe field with a standing-wave pump and a second control laser field in four-level atomic media of N type. ... -
Raman Spectroscopy Study of the Behavior of the Soft Mode in a Structural Phase Transition in the Pr3Sb5O12 Crystal
Орешонков, А. С.; Ходжибаев, А. К.; Крылов, А. С.; Умаров, М. Ф.; Втюрин, А. Н.; Oreshonkov, A. S.; Khodzhibaev, A. K.; Krylov, A. S.; Umarov, M. F.; Vtyurin, A. N. (2015-11)The structural phase transition in the Pr3Sb5O12 crystal has been studied using Raman spectroscopy. The phase transition is accompanied by the recovery of the soft mode below T = 735 K, which is associated with the ... -

Evidence for CO Disproportionation over Ceria during Oxygen Storage Capacity Measurements: an in Situ Raman Spectroscopic Investigation
Swanson, Meghan; Pushkarev, Vladimir V.; Kovalchuk, Vladimir I.; d’Itri, Julie L. (Сибирский федеральный университет. Siberian Federal University, 2008-04)The interaction of CO with ceria under conditions typical for oxygen storage capacity (OSC) measurements of three way catalysts (TWC) has been investigated by in situ Raman spectroscopy. It has been shown that CO ...
