    • In the presence of DM interactions, S>0 spin states might become Raman active. However, we are not concerned here with such excitations which (i) lie at higher energies than the energy range considered here and (ii) would only carry a small spectral weight. In addition, (iii) a perturbative DM interaction has an even weaker effect on the Raman-active low-energy singlet-like excitations.
