Conceptual Shift in Our Understanding of Degenerate Radical Spin Systems: Spin-Rotation Coupling Turned on Its Head.
For most chemists, Kramers' degeneracy refers to the fact that for any radical system, every potential energy surface is at least doubly degenerate (with spin up and spin down, time-reversed solutions) for all nuclear positions X. Yet, as is well-known to the community of spin chemists, one can experimentally detect a...
