Rydberg excitons, characterized by large spatial extension and reduced electron-hole overlap, must have a spin dynamics different from that of ground state excitons. However very little is known about their spin relaxation. We report a direct measurement and interpretation of the spin dynamics of Rydberg excitons in high-quality WSe₂ monolayer.
