The question of coloring : Calculations present a definite solution to the “coloring problem” in the MB 2 C 2 phases (M=Mg, Sc, Ca, Y, Ln; see picture of the four structure types). Electric‐field gradient tensor components from NMR spectroscopy readily allow differentiation between the different B/C topologies and give support to the theoretical results.
