    Description / Table of Contents: By a new technique the CCl3 radical is isolated from the gaseous state at -190°C. Its preparation may be represented by the reactions mentioned above. As CCl3Br when treated with bromine, and also as the dimer C2Cl6. Its IR spectrum shows a strong band v3 (CCl3) at 895 cm-1 (along with a satellite at 869 cm-1), indicating that very probably the molecule belongs to the symmetry group D3h.
    Notes: Es wird eine Untersuchungstechnik beschrieben, mit deren Hilfe das Radikal CCl3 in der Gasphase (0,05 Torr) dargestellt und bei -190°C isoliert und spektroskopisch nachgewiesen werden kann.

Die wahrscheinliche Symmetrie des CCl3 ist die der Punktgruppe D3h.
