The resultant Zeeman splittings of the two low levels of Sn/sup 119/ were measured by observing the hyperfine spectra in the resonant absorption of the 24-kev radiation of Sn/sup 119/. In Mn/ sub 4/Sn an internal field of roughly 40 koe was found. In this field the splitting of the ground state was observed but that of the excited state was unresolved. In Mn/sub 2/Sn an internal field of about 190 koe was produced. In this field additional structure was obtained which was attributed to the splitting of the excited state. The measured splitting gave a value of (0.78 plus or minus 0.08) nm for the magnetic moment of the excited state.
