In EPR the magnetic dipole of an electron interacts with an external magnetic field and can be excited by an oscillating magnetic field. Spin labelling involves use of extrinsic probes, nitroxides, attached to the molecule under study. The spectra of nitroxide probes are used to infer orientation, dynamics and distances between labelled sites.
