In order to determine the molecular structure and barrier to internal rotation of the GeH3 group, the microwave spectra of (chloromethy)germane and its deuterated species ClCH2GeD3 have been investigated. From splittings of the spectra due to the first excited GeH3 torsional state, the barrier to internal rotation was determined to be 1740±30 cal/mol. Assuming the cylindrical symmetry of the C–Cl bond, the quadrupole coupling constant was determined to be χzz=−74.7 MHz for the 35ClCH274GeH3 species.
