  • Davydov multiplets in vibrational spectra of and crystals 
    SYRBU, N. N.; CEBOTARI, V. Z. (IOP Publishing, 1998)
    In this paper the Raman vibrational spectra for all actually realized geometries of and crystals at 77 K, and infrared reflectivity spectra for both and polarizations in the range from 50 to at 300 K have been investigated. ...
  • Oblique Phonons in Raman Scattering and IR Reflection of TeO2 Crystal 
    SYRBU, N. N.; CRETU, R. V.; CEBOTARI, V. Z.; MUSHINSKII, V. P. (WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim, 1996)
    The Raman scattering and IR reflectivity have been investigated for different crystal configurations. The contours of reflectivity spectra have been calculated. The angle dependence of polar vibrational modes in both ...
  • Polar vibrational modes in Ag3AsS3 crystals 
    SYRBU, N. N.; CEBOTARI, V. Z.; BOGDANASH, M. (Elservier, 1996)
    Reflectivity spectra of Ag3AsS3 crystals have been investigated in the range from 50 to 4000 cm−1 for E∥÷c and E ⊥ c polarizations, and practically all expected vibrational modes of A1 and E symmetry have been found. Phonon ...
  • The superposition of the lattice radiation and reflectivity spectra of tetragonal TeO/sub 2/ crystals 
    SYRBU, N. N.; RADAUTSAN, S. I.; CRETU, R. V.; MUSHINSKII, V. P.; CEBOTARI, V. Z. (IEEE, 1995)
    The superposition of infrared reflectivity spectra end lattice radiation of TeO/sub 2/ crystals have been investigated. Both radiation spectra at high temperatures and absorption spectra in the two-phonon range for ...
