Electron spin-lattice relaxation: the direct and Raman process of spin 1/2 systems

Electron spin-lattice relaxation represents the interface between the spin on paramagnetic centres -- transition metal ions, radicals, defects etc. -- and lattice vibrations. This interface is indirect and requires two interactions: the spin-orbit interaction between the spin and the orbits of the paramagnetic centres and the orbit-lattice interaction between the latter and the lattice. The purpose of this talk is to provide an overview of all these elements of the process and to show how the spin-orbit interaction relates the relaxation rates to the deviation of the g-factor from that of a free electron spin.
