Magnetic susceptibilities of soluble actinide ions were revisited by NMR spectroscopy. Experimental values are compared with previously published values. An estimated order of magnitude of the paramagnetic effects can be used as probes in NMR spectroscopy. Lanthanide(III) ions are discussed in the context of 4f and 5f electrons. Measurements performed on other actinide oxidation states (IV, V, and VI) emphasize the importance of water ligand field effects on the 5f electrons.
