The layered ternary compound TaIrTe4 is an important candidate to host the recently predicted type‐II Weyl fermions. However, a direct and definitive proof of the absence of inversion symmetry in this material, a prerequisite for the existence of Weyl Fermions, has so far remained evasive. Herein, a...
