Abstract The hyperfine structure of the ground state 4d 5 5s 7 S 3 of95Mo and97Mo has been measured by the atomic beam magnetic resonance technique with the following results:95Mo:A=−208.582060(10)MHz,B=37.050 (100) kHzC=−30 (10) Hz,D=−3 (3) Hz97Mo:A=− 212.980930 (10) MHz,B−69.990(140)kHzC=−5 (10) Hz,D=0 (3) Hz. After application of corrections calculated according to second order perturbation theory, the hyperfine structure constants became:95Mo: Ac=−208.582560(290)MHz,B c =16.920(4300)kHzC c=−30(270) Hz,D c =− 3 (50) Hz97Mo: Ac=212.981450(300) MHz,B c =−90.780(4400)kHzC c=−6(270) Hz,D c =0 (50) Hz. With the known ratio ofg I(95Mo)/g I(97Mo) [1] a calculation of the hyperfine anomaly yields:95 Δ 97=−0.01009(17)%. The ratio of the uncorrectedB factors isB(97Mo)/B(95Mo)=−1.8890(47). Because of the relatively large effects of second order hyperfine structure, the ratio of the correctedBfactors differs considerably from the ratio of the uncorrectedB factors. From the correctedB factors the electric quadrupole moments may be evaluated by means of calculated radial integrals [2]. The results are:Q (95Mo)=−0.019(12)barns,Q(97Mo)=0.102(39)barns.
