The 4f orbitals of Gd3+ ion are half-filled. This sort of unique electronic structure makes it behave the largest ground spin state and completely quenched orbital momentum over all the possible ions in the periodic table. Based on the introduction of the electronic structure of Gd3+, this paper briefly discusses the application of Gd3+ in the field of nuclear magnetic resonance imaging contrast agent and molecule qubit.

Key words: Gadolinium, MRI contrast agents, Molecular qubits
