Abstract

Matrix infrared and laser Raman spectra are reported for GeF2 and (GeF2)2 in both N2 and Ar matrices. Raman depolarization measurements for the monomer in N2 matrices identify ?1 at 653 cm-1. Warm-up experiments identify infrared and Raman lines at 665, 478 cm-1 and 669, 465, and 424 cm-1 respectively, with the first stage of the polymerization of GeF2 monomer and are assigned to GeF stretching modes of the dimer (GeF2)2, having a centrosymmetric C2h, non-planar structure, containing a double fluorine bridge similar to the structure proposed for (SeO2)2. A normal coordinate analysis is performed on the dimer using a force field transferred from the monomer. The results provide additional evidence for the correctness of the vibrational and stereochemical assignments for the dimer.
