This paper investigates chiral Raman scattering in monolayer transition metal dichalcogenides with triclinic symmetry. The authors demonstrate that quantum interference between Raman scattering pathways excited by circularly polarized light leads to a significant chiral Raman response. Large circular intensity differences observed in monolayer rhenium dichalcogenides originate from inter-k interference. The findings reveal chiral Raman spectra as a new manifestation of quantum interference in Raman scattering and suggest the potential for inducing chiral optical response in other materials.
