Abstract

Calcium alumino-silicate glasses were investigated by infrared reflectivity and polarized Raman scattering. Vibrational modes were assigned to different types of atomic motion in the glass network. The nature of the low frequency Raman peak or Boson Peak is discussed in terms of existing theories. Kramers-Kronig analysis was performed on IR reflectivity data to extract longitudinal and transverse optic phonon frequencies.
