The principal results of the work are as follows: 1. A simplified
technique was devised for obtaining Raman spectra of powders. 2.
The Raman and infrared absorption spectra of the following oxides
were investigated: AsP3' SbP3' As 0 * SbP5. Te02. Ge02 (two forms)
in the crystalline state, and ASP3' Ge02' Te0 in the glassy state.
2 5 2 3. The vibrational spectra of the crystalline and glassy
forms of the oxides ASP3' Ge02' Te02 are simi- lar in many main
respects, indicating a similarity of their structural units which
determine the vibrational spec- tra of these substances. 4. By a
study of the vibrational spectrum it was shown that arsenious
anhydride has a molecular structure and consists of As0 molecules
having symmetry of the point group Td' The force constants and
vibration fre- 4 6 quencies of the As 0 molecule were calculated.
and the vibrational spectrum of arsenious anhydride was re- 4 6
liably interpreted with the aid of these results. 5. A similar
result was obtained for antimonous anhydride. consisting of Sb0
molecule.s with symmetry 4 6 ofthe point group Td. The force
constants for this molecule were found and the vibrational spectrum
was calculated.
