Abstract
Phonon Raman scattering spectra of Sr2RuO4 have been measured in the t emperature region between room temperature and 5 K. Three symmetry-all owed phonons have been observed at room temperature. Since similar spe ctra have been observed at low temperature, Sr2RuO4 does not undergo s tructural phase transitions in the temperature region. The energy of t he phonon modes has been calculated by a GF matrix method. The force c onstants along the c-axis of Sr2RuO4 are larger than those for La2-xSr xCuO4.
