Volume 25: Optical Methods of Investigating Solid Bodies

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.
