 Title    Kraftkonstanten, mittlere Schwingungsamplituden, Coriolis-Kopplungskonstanten und thermodynamische Funktionen der Moleküle W OCl4 und WOBr4  
 Abstract    A normal co-ordinate analysis of the m olecules W 0C 14 and WOBr4 has been carried out follow ing W ilson's FG matrix method. V alence force constants based on known (W OCl4) and estimated (W OBr4) m olecular parameters have been evaluated. The results support the assignm ent of the known Raman spectra of W 0C14 . A lso the m ean am plitudes of vibration and the perpendicular

 Title    Schwingungsberechnungen der isotopen VOCl3-Moleküle, des VOBr3 und der Verbindungen VOCln Br3_n, sowie einige Molekularkonstanten der Titelverbindungen  
 Abstract    In order to determine the isotopic splittings of the vibrational frequencies of isotopieally sub­ stituted vanadium oxytrichloride and to present the correlation between V0C13 and VOBr3 a set of force fields was constructed for the isotopic species of VOCl3 , VOCLBr, VOCIBr, and VOBr3 . The conventional descriptions of the fundamentals are supported by the calculated potential energy distribution in all cases. Furthermore the calculations of certain molecular constants such as the mean amplitudes, their corresponding /^-values, the Coriolis coupling constants of the -type and some thermodynamic quantities have been performed.
