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.\u003c\/p\u003e","brand":"Springer","offers":[{"title":"Paperback","offer_id":45282679259287,"sku":"9781468472080","price":3633.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/3471\/1191\/files\/9781468472080.webp?v=1769302852","url":"https:\/\/atlanticbooks.com\/products\/volume-25-optical-methods-of-investigating-solid-bodies-9781468472080","provider":"Atlantic Books","version":"1.0","type":"link"}
