Microwave spectrum of (trifluoromethyl)germane, CF3GeH3

摘要

Microwave spectra of five isotopic species of CF3GeH3have been investigated in the region 15 000 to 31 000 MHz. The height of the potential barrier hindering the internal rotation was determined to be 1280plusmn;150 calsol;mole, using the frequency method for rotational satellite transitions. Thesymhyphen;symcase of hindered internal rotor molecules is discussed, and expressions are given for calculating barrier heights using tabulated quantities.
