The Microwave Spectrum, Structure, Dipole Moment and Quadrupole Coupling Constant of Germyl Cyanide

摘要

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)
