Abstract
The observation of the precession frequencies of individual paramagnetic spins with the scanning tunneling microscope is explained here by a spin-orbit-coupling mechanism. The dangling-bond defect is excited into a superposition of eigenstates by the tunneling electrons. The charge density of the dangling bond will therefore be time dependent. Due to the spin-orbit coupling, frequencies close to the precession frequencies will appear in these oscillations, and the tunneling current will have oscillating components that are related to the precession frequency.
