Abstract A molecular beam resonance apparatus with electric quadrupole lenses asA- andB-fields and with superimposed parallel electric and magnetic transition-fields was used. Molecules in different rotational statesJ, m J are separated by theA-field. Spectra of molecules in different vibrational states are resolved by their different Starkeffect energies. By this means the following electric and magnetic properties of the molecule could be measured in the rotational stateJ=1 and vibrational statesv=0 and 1: The magnetic and electric dipole moment of the molecule, the scalar and the tensor nuclear dipole — dipole interactiond s andd T, the nuclear spinrotational interactionc F andc Rb, the nuclear quadrupole interactioneqQ, the nuclear magnetic moment μRb, the anisotropy of the diamagnetic susceptibility ξ⊥−ξ∥, the anisotropy of the diamagnetic shielding of the external field by the electrons at the position of the nuclei σ⊥−σ∥. Using these quantities it was possible to calculate the quadrupole moment and a weighted quadrupole moment of the electronic charge distribution. The results are: (J=1,v=0) μel=8,5464 (17) debμ J/J=−29,79(2)x10−6 μ B d s/h=0,36(23) kHzd T/h=0,69(22)kHzc F/h=10,42(70) kHzc Rb/h=0,479 (48) kHz.eqQ Rb/h=−70,3410(26) MHzμ(1−σS)Rb=1,3474(5) μk (ξ⊥-ξ ∥)=12(6)×10−30 erg/Gauß2 (σ⊥-σ∥)Rb=−3,8(2,1)×10−4 (σ⊥-σ ∥)F=−2,6(3)×10−4
