Nuclear Moments of ${\mathrm{Mo}}^{95}$, ${\mathrm{Mo}}^{97}$, ${\mathrm{Zr}}^{91}$, ${\mathrm{I}}^{127}$, ${\mathrm{Sb}}^{121}$, and ${\mathrm{Sb}}^{123}$

The hyperfine structure (hfs) of the spectrum of Mo i was studied, and it was found that both ${\mathrm{Mo}}^{95}$ and ${\mathrm{Mo}}^{97}$ have nuclear spins equal to $\frac{7}{2}$. Substituting this in the $g$-values of ${\mathrm{Mo}}^{95}$ and ${\mathrm{Mo}}^{97}$ given in the literature, the magnetic moments $\mu \left({\mathrm{Mo}}^{95}\right)=-1.2736\mathrm{}$ nm and $\mu \left({\mathrm{Mo}}^{97}\right)=-1.3006\mathrm{}$ nm (without diamagnetic correction) are obtained. Hfs investigation of the spectrum of Zr i yielded the result that $\mu \left({\mathrm{Zr}}^{91}\right)=-1.9\mathrm{}\pm 0.2$ nm. The quadrupole moment of ${\mathrm{I}}^{127}$ as derived from the hfs of the visible spectrum and as derived from the atomic beam resonance technique published in the literature is discussed, and it is concluded that $Q\left({\mathrm{I}}^{127}\right)=(-0.69\mathrm{}\pm 0.03)\times {10}^{-24\mathrm{}}$ ${\mathrm{cm}}^2$ including the polarization correction due to Sternheimer. Data concerning the hfs of the spectrum of Sb ii are discussed, and it is shown that they support the values $Q\left({\mathrm{Sb}}^{121}\right)=(-0.53\mathrm{}\pm 0.10)\times {10}^{-24\mathrm{}}$ ${\mathrm{cm}}^2$ and $Q\left({\mathrm{Sb}}^{123}\right)=(-0.68\mathrm{}\pm 0.10)\times {10}^{-24\mathrm{}}$ ${\mathrm{cm}}^2$ (including the polarization correction) that were deduced previously.
