Elektrisches Dipolmoment und Mikrowellenrotationsspektrum des GeO und GeS

Abstract

Stark-effect measurements on pure rotational transitions of GeO and GeS are described. Measurements on the ground vibrational state of the most abundant isotopic molecules resulted in the following electric dipole moments: 74Ge18O μ = (3,28±0,10) D; 74Ge32S μ = (2,00 + 0,06) D . Due to improved resolution and sensitivity of the spectrometer, the rotational spectra of GeS were measured in more detail and with greater accuracy than previously. The derived rotational constants, Y01 , Y11, Y21 and Y02 , are reported.
