TL;DR: In this paper, the infrared spectra of the isostructural MVO3 compounds (M=K, Rb, Cs, Tl, NH4), consisting in an array of infinite tetrahedral chains, are reported and discussed with the aid of a simplified factor group analysis.
Abstract: The infrared spectra of the isostructuralMVO3 compounds (M=K, Rb, Cs, Tl, NH4), consisting in an array of infinite tetrahedral chains, are reported and discussed with the aid of a simplified factor group analysis. In the case of NH4VO3 also the laser-Raman spectrum was recorded and analyzed. Force constants, mean amplitudes of vibration and other bond properties for the terminal VO2 groups, as well as for the VOV chain units are estimated.

TL;DR: In this article, a spektroskopischen Untersuchung of Oxoanionen des Tellurs is presented, in which einige einfachen Zuordnungskriterien angewandt welche sich im Falle von Oxoanions der Uber- gangsmetalle sehr gut bewahrt haben.
Abstract: Da uber die Schwingungseigenschaften von Oxoanionen des Tellurs noch verhaltnismasig wenig bekannt ist [1 , 2], beschaftigen wir uns gegenwartig mit der spektroskopischen Untersuchung solcher Spezies. Unter den einfachen Oxoanionen des Tellurs ist das Te(>42~ besonders interessant. Fur dieses Ion wurde namlich schon seit langerer Zeit tetraedrische Koordination des Tellurs vermutet [3], obwohl gewohnlich bei Te(VI)-Verbindungen fast immer oktaedrische Koordination vorliegt [1]. Die tetraedrische Koordination konnte aber tatsachlich durch eine jungst durchgefuhrte schwingungsspectroskopische Untersuchung an K 2Te0 4 , Rb2Te04 und Cs2Te04 eindeutig bestatigt werden [4], obwohl es nicht moglich war eine Totalzuord nung des gesamten Spektrums durchzufuhren. Wahrend die Zuordnung der beiden Streckschwingungen sowohl an Hand der Raman-Intensitaten wie auch durch Anwendung eines allge meinen Zuordnungskriteriums [5] gesichert ist und vs > vi ergibt, ist die Zuordnung im Bereich der Deformationsschwingungen weitaus schwieriger [4], Uns gelang es jetzt aber auch in diesem Bereich eine endgultige Zuordnung zu treffen. Hierzu haben wir einige einfache Zuordnungskriterien angewandt welche sich im Falle von Oxoanionen der Uber gangsmetalle sehr gut bewahrt haben [6, 7]: a) das r4/r2-Frequenzenverhaltnis mus fur Te042_ groser als beim isoelektronischen J 04sein und b) das
