Infrared absorption of glassy silicon dioxide

  • M. Miler


The infrared reflectivity of glassy silicon dioxide has been measured in the region of 2–35 μm at room temperature. The reflectivity curve has been analyzed by means of Kramers-Kronig analysis and the optical constants have been determined. In addition to the three known peaks at 9 μm, 12·5 and 22·5 μm, the absorption curve exhibits further peaks at 17·5 and 11 μm. A correlation with the transmissivity measurements has shown that in this region even the transmissivity curve exhibits a decrease. An attempt has been made at an interpretation of the spectrum according to Matossi's model of vibrations of the free tetrahedron SiO4.
