Stimulated x-ray Raman scattering for selective preparation of dark states bypassing optical selection rules

Year: 2025

Type: article

Abstract: We present an X-ray based stimulated Raman approach to control the preparation of optically dark electronic states in generic molecular systems. Leveraging on the unique properties of core-level excited states, we demonstrate that optically forbidden transitions between singlet states, or between singlet and triplet states are made accessible. Two molecular systems are studied as a test-bed of the proposed approach, and its experimental feasibility is eventually discussed.
