Abstract : The symmetric top spectra of ten isotopic species of GeH3CN were observed and measured. From the rotational constants obtained the following structural parameters were derived: r(C-N) = 1.55 plus or minus 0.001 A and r(Ge-C) = 1.919 plus or minus 0.001 A, assuming r(Ge-H) = 1.529 A and a tetrahedral distribution about the Ge atom. From an analysis of the splittings observed in the 1 to 2 transitions of GeH3CN a quadrupole coupling constant for the nitrogen nucleus of -5.0 plus or minus 0.1 Mc/s was obtained. Analysis of the Stark effect gives a dipole moment of 3.99 plus or minus 0.05 D. (Author)
