    Notes: During the technical important combustion of SiCl4 with oxygen [SiCl4(g) + O2(g) = SiO2(s) + 2·Cl2(g)] many intermediates have been detected in the past. However, the presence of the primary species O=SiCl2 has been discussed controversially until today. With the help of matrix isolation technique we have now been successful to monitor O=SiCl2 via its IR spectrum. With the help of quantum chemical calculations the thermodynamic data have been calculated first. On this basis it was possible to find the optimal conditions to trap OSiCl2 from the high-temperature equilibrium. Furthermore it could be shown via IR spectroscopy and quantum chemical calculations, that the radical OSiCl does not play a significant role within this combustion process.

    Sonochemie: Bildung von C3S2 neben Sx (x = 6, 7, 8) durch Einwirkung von Ultraschall auf CS2Professor Gerhard Thiele zum 60. Geburtstag gewidmet (1996)

    Description / Table of Contents: Sonochemistry: C3S2 Originated by Ultrasounding CarbondisulfidePure carbondisulfide was treated with ultrasound of a frequency of 20 kHz. Consequently small amounts of C3S2, S6, S7, and S8 were obtained, which could be separated gas-chromatographically and detected by mass spectroscopy. The yields were approximately proportional to the period of influence.
    Notes: Die Beschallung von Schwefelkohlenstoff mit Ultraschall (20 kHz) führt zu stationären, kleinen Konzentrationen an C3S2, S6, S7 und S8, die gaschromatographisch getrennt und massenspektrometrisch identifiziert werden. Die Ausbeuten der Produkte sind in erster Näherung proportional zur Beschallungsdauer.
