An overview of some recent results on nuclear moment measurements on isomers is being given. Neutron rich isomers have been produced in a fragmentation reaction at GANIL. Using the spin-orientation of the fragment beam, isomeric g-factors around 68Ni have been measured by detecting the Larmor precession via the isomeric \gamma -decay (TDPAD-method). Isomers in the mass A\sim 180 region were produced in a fusion-evaporation reaction at Louvain-la-Neuve. The quadrupole moment of a 5 quasi-particle isomer in the deformed nucleus 179W was measured using the Level Mixing Spectroscopy (LEMS) method. Both results show how details on the nuclear structure can be investigated via nuclear moment measurements.
