Recently , (open access) studied a resonant Raman scattering spectrum in the case of bilayer 2H-MoS2 encapsulated in hexagonal BN flakes. The resonant spectrum "as initiated by the laser energy of 1.96 eV, close to the A excitonic resonance, shows rich and distinct vibrational features that are otherwise not observed in non-resonant scattering". The spectrum shows the Raman-active modes E 1 2g and A1g and "their Davydov-split counterparts" E1u and B1u. The split between modes A1g and B1u is approximately 3 cm -1 , and, according to Bhatnaga and coworkers, it is in agreement with the Davydov splitting reported earlier by Na et al., 2018, and Shinde and Eswaran, 2021. According to Shinde and Eswaran, the near resonance with the A excitonic transition (1.96 eV) "resulted in a Davydov splitting of the out-of-plane A-like phonon mode (A1g) around 406 cm -1 caused by the weak interlayer interaction. The number of Davydov splitting components (N) equals the number of layers (NL) of the MoS2, suggesting that it can be used as a thickness indicator".
