Here, we report, for the first time, on the first‐order Raman spectra of the layered Mo‐based ternaries: MoAlB, Mo 2 Ga 2 C and Mo 2 GaC. Polycrystalline samples were fabricated, and well‐defined Raman spectra were recorded. When the experimental peak positions were compared with those predicted from density functional theory, good agreement was obtained, indirectly validating both. Furthermore, all modes in the three compounds were symmetry assigned. Copyright © 2017 John Wiley & Sons, Ltd.
