We determine the CEF Hamiltonian by fitting to neutron scattering data using a point-charge Hamiltonian as an intermediate fitting step. The fitted Hamiltonians accurately reproduce bulk susceptibility measurements, and the results indicate easy-axis ground state doublets for $\\rm{Nd_3Sb_3Mg_2O_{14}}$ and $\\rm{Nd_3Sb_3Zn_2O_{14}}$, and a singlet ground state for $\\rm{Pr_3Sb_3Mg_2O_{14}}$.
