    Description / Table of Contents: Infrared Spectroscopic Evidence for Monomeric HGaCl2 in Solid ArgonMolecular HGaCl2 is found in a matrix between the hightemperature molecule GaCl and HCl. A structure analogous to that of phosgene can be derived from the isotopical shifts (H/D, 69Ga/71Ga and 35Cl/37Cl) within the IR spectra. The normal coordinate analysis results for the GaCl force constant a value of 2.52 mdyn/Å and for the GaH force constant a value of 2.38 mdyn/Å.
    Notes: Molekulares HGaCl2 entsteht in einer photochemischen Reaktion aus dem Hochtemperaturmolekül GaCl und HCl in festem Argon. Die Lage der IR-Absorptionen und die H/D-, 69Ga/71Ga- bzw. 35Cl/37Cl-Verschiebungen weisen auf eine Spezies mit C2v-Struktur hin. Die Normal-koordinatenanalyse liefert für die GaCl-Bindung eine Kraftkonstante von 2,52 mdyn/Å und für die GaH-Kraftkonstante einen Wert von 2,38 mdyn/Å.
