Not all are created equal: Analysis of the ELNES of boride carbides such as CaB 2 C 2 permits us to determine the arrangement of boron and carbon atoms. Through this method, characteristics of the crystal structure which cannot be obtained by diffractory methods are made available. The spectra shown reveal clear differences between (bottom to top) the measured B K ionization edge of CaB 2 C 2 and those calculated for CaB 2 C 2 , LaB 2 C 2 , and CeB 2 C 2 .
