AbstractWe report the experimental studies of the vibrational spectra of SrTiO3 films with the thickness of 1 µm grown by pulsed laser deposition. Fourier-transform infrared ellipsometry between 30 and 700 cm−1 and electric field-induced Raman scattering have been utilized for investigation of the phonon behavior. These results can be used for comparison with the low-frequency measurements of the static dielectric constant. In the films, the soft mode reveals hardening compared to that in bulk crystals. This observation is in agreement with the Lyddane-Sachs-Teller formalism.

The far infrared spectra of Ni (pyridine)4X2 and Ni(γ-picoline)4X2 (X = CI, Br and I) have been measured. The Ni-X and Ni-N stretching bands have been assigned based on isotopic shifts due to the 58Ni-62Ni, pyridine-pyridine-d5, and Cl-37Cl substitutions.
