Transition metal ion compounds that have an orbital degree of freedom have recently been the focus of much attention owing to the importance that spin-orbit coupling plays in the creation of new phases and excitations. We will outline a series of scattering studies illustrating the role that neutrons have in characterizing spin-orbit physics in transition metal compounds. Particular focus will be given to third-row transition metal ions where spin-orbit coupling is of a similar energy scale to symmetric exchange coupling and distortion terms in the magnetic Hamiltonian. We will outline a formalism to understand these excitations based on single-ion physics which, due to the spatially diffuse nature of orbitals, we term spin-orbit excitons. This approach treats single-ion physics, exchange, and distortion terms equally and we will discuss examples applied to compounds containing V3+, Fe2+, and Co2+ containing materials.
