Abstract
Microwave spectra of three isotopic species of CH2FGeH3 have been investigated in the region 8000–30 000 MHz. The height of the potential barrier hindering the germyl group (GeH3) internal rotation was determined to be 1390±40 cal/mole from measured A‐E frequency differences, using a PAM calculation through fourth‐order perturbations. Dipole moment components μa = 1.00 D, μb = 1.30 D, giving a resultant μ = 1.64±0.03 D, were obtained from Stark effect measurements. A technique for assigning R‐branch asymmetric rotor transitions is discussed.Keywords
