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\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9781468472080\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9781468472080","offer_id":39417346555997,"sku":"9781468472080","price":53.49,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/2eede027-ebe5-4270-a1a6-5dbda720ad7d.jpg?v=1775880189","url":"https:\/\/shop.autorenwelt.de\/en\/products\/volume-25-optical-methods-of-investigating-solid-bodies-von-d-v-skobel-tsyn-hrsg","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
