    Description / Table of Contents: The complete vibration spectra of Cl3SiF, Br3SiF, and J3SiF were registrated and assigned. As expected, the force constant of the bond Si—F diminishes with descreasing electronegativity of the other atoms bound to silicon.
    Notes: Die vollständigen Schwingungsspektren von Cl3SiF, Br3SiF und J3SiF wurden aufgenommen und zugeordnet. Die Kraftkonstante der Si—F-Bindung veringert sich erwartungsgemäß mit abnehmender Elektronegativität der übrigen Bindungspartner des Siliciums.

    Schwingungsspektroskopische Untersuchungen zur Struktur des TIF (1969)

    Description / Table of Contents: For TIF the IR- and RAMAN spectra have been recorded. The observed selection rules show that TIF does not belong to the space group D2h23 but presumably to C2v18. The sites of the anions are estimated by BADGERS'S rule. A band at 475 cm-1 is assigned to monomeric TIF which seems to be present in the lattice in small quantities.
    Notes: Die IR- und RAMAN-Spektren des TIF wurden aufgenommen. Aus den beobachteten Auswahlregeln folgt, daß TIF nicht der Raumgruppe D2h23 sondern wahrscheinlich C2v18 angehört. Die Punktlagen der Anionen lassen sich mit der Badger-Regel abschätzen. Eine Bande bei 475 cm-1 wird dem „monomeren“ TIF zugeordnet, das im Gitter in geringer Menge vorzuliegen scheint.

    Die Infrarot- und RAMAN-Spektren der Alkalifluorosulfate (1970)

    Description / Table of Contents: For the alkali fluorosulfates MSO3F infrared spectra (M = Li, Na, K, Rb, Cs) and also RAMAN spectra (M = K, Rb, Cs) have been recorded. The results are discussed to get some information about the lattice structures. The C3 axis of the anion has several possibilities of orientation in the unit cell for the salts with heavy cations.
    Notes: Die Infrarotspektren der Alkalifluorosulfate MSO3F sowie die Raman-Streuung für M = K, Rb und Cs wurden aufgenommen. Die Ergebnisse werden diskutiert und zu einigen Aussagen über die Gitterstrukturen benützt. Die dreizählige Achse des Anions bei den schwereren Salzen besitzt mehrere Orientierungsmöglichkeiten in der Einheitszelle.

    Description / Table of Contents: Vibrational Spectra and Force Constants of Symmetric Tops. XXI. Rovibrational Spectrum of CF379Br and CF381Br in the v2 RegionThe rovibrational spectrum of CF379Br and of natural CF3Br has been recorded in the region of the fundamental v2 near 750 cm-1 in the i.r. with a resolution of 0.04 cm-1. From the analysis of the spectra the values of v0, the anharmonicity constants x23, x25 and x26 as well as B″ and B′ from the J structure have been obtained both for CF379Br and CF381Br. v2 displays Fermi resonance with 2v3 which is located near 700 cm-1.
    Notes: Das Schwingungs-Rotations-Spektrum von CF379Br und natürlichem CF3Br wurde im Bereich der Grundschwingung v2 nahe 750 cm-1 im IR mit einer Auflösung von 0,04 cm-1 aufgenommen. Aus der Analyse der Spektren konnten für CF379Br und CF381Br v0, die Anharmonizitätskonstanten x23, x25 und x26 sowie aus der J-Struktur die Werte B″ und B′ ermittelt werden. v2 steht in Fermi-Resonanz mit 2v3 bei ∼700 cm-1.

    The sodium chloride primary pressure gauge (1976)
    In:  Other Sources
    Details
    Publication Date: 2019-06-27
    Description: The failure of a central force model for sodium chloride is discussed. It is noted that it does not closely satisfy the Cauchy conditions at low temperatures, and that it fails the central force requirement of the Love condition. The available shock data for sodium chloride and its analysis is examined, and two reasons why the Hugoniot transformation pressure is likely to be less than 231 kbar are discussed. The important (but unjustified) theoretical assumptions made in converting Hugoniot to isothermal data is discussed; it is noted that serious error can enter for very large pressures for a given material and that at such high pressures the isothermal data should thus be considered only semiquantitative even if the Hugoniot data itself is accurate. An alternate method of estimating the isothermal transformation pressure from the Hugoniot transformation pressure is used. This method is based on the temperature derivative of the transformation pressure. On this basis it is concluded that an upper bound for the isothermal transformation of NaCl (to a CsCl-type structure) at room temperature is 257 kbar; it is noted that the actual value may be considerably less than this.
