Sažetak
Resonant inelastic x-ray scattering at the NK edge reveals clearly resolved harmonics of the anion plane vibrations in the κ-(BEDT-TTF)2Cu2(CN)3 spin-liquid insulator. Tuning the incoming light energy at theK edge of two distinctNsites permits us to excite different sets of phonon modes. The cyanide (CN) stretching mode is selected at the edge of the ordered N sites which are more strongly connected to the bis(ethylenedithio)tetrathiafulvalene (BEDT-TTF) molecules, while positionally disordered N sites show multimode excitation. Combining measurements with calculations on an anion plane cluster permits us to estimate the site-dependent electron-phonon coupling of the modes related to nitrogen excitation.
