of a system containing π dimers of identical molecular radical ions measured with laser
excitation in resonance with the charge transfer (CT) transition. A Peierls–Hubbard (PH)
Hamiltonian has been used to model the investigated system and to calculate its optical and
RRS properties. Results are reported for two polyoxometallate salts of tetrathiafulvalene
(TTF), namely (TTF) 2 (W6O19) and (TTF) 2 (Mo6O19) whose structures contain almost …
