报道了用单晶研究Yb基重费米子系统中的核磁共振(核磁共振)和核四极共振(NQR)。在B||a，b，c的每个晶轴上观察到了清晰的12 1条Sb核磁共振谱线。通过与观测的Sb核磁共振谱和数值模拟的比较，获得了10K下的电场梯度参数和奈特移参数。获得的奈特移张量的四极频率、非对称参数、各向同性奈特移和各向异性主值为νq=18.8 MHz，$Eta=0.2，Text{hspace{0.17em}}{K}{{ISO}}\约0.6
We report a study of 121 Sb nuclear magnetic resonance (NMR) and nuclear quadrupole resonance (NQR) in a Yb-based heavy fermion system YbRhSb using a single crystal. Sharp 121 Sb-NMR lines were observed for each crystal axis for B|| a, b, c. From comparison with observed Sb-NMR spectra and numerical simulations, electric field gradient (EFG) parameters and Knight shift parameters are obtained at 10 K. The obtained quadrupole frequency, asymmetry parameter, isotropic Knight shift and anisotropic principal values of Knight shift tensors are ν Q= 18.8 MHz, $\eta= 0.2,\text {\hspace {0.17 em}}{K} _ {{iso}}\approx 0.6\% $
