Matrixreaktion von GeO mit F2. IR-spektroskopischer nachweis von molekularem OGeF2

GeO reacts with F₂ in an argon matrix after photolysis with a high-pressure mercury lamp to form OGeF₂. Isotopic splitting (¹⁶O/¹⁸O and ⁷⁰Ge/⁷²Ge/⁷⁴Ge) and force constant calculations show that the fundamentals observed can be assigned to a planar molecule OGeF₂. The value of the force constant of the GeO double bond, 7.43 × 10² N m^?1, is as expected (GeO₂ 7.32 × 10² N m^?1), but the GeF bond is unexpectedly weak (f_GeF = 5.01 × 10² N m^?1).
