Abstract
The Zeeman effect in the microwave rotational spectrum of 63Cu19F and 69Ga19F has been measured in the ground vibrational state υ = 0 in order to determine the (gJ-factor and the molecular magnetic susceptibility anisotropy ξT : 63Cu19F: gJ = -0.0628(2) ; ξT/h = 540(60) Hz/(kG)2 ; 69Ga19F: gJ = -0,06012(12) ; ξT/h = 521 (17) Hz/(kG)2. The molecular quadrupole moment and its electronic part are derived from the values of gJ,ξT and the rotational constant B0 . - The hyperfine structure of the Zeeman lines enabled a more or less rough determination of the magnetic shielding anisotropy of the nuclei 63Cu and 69Ga respectively: σT(63Cu) = -1760(830) · 10-6 , σT (69Ga) = - 386(165)·10-6.Keywords
