Total energies of MoN have been calculated for small strains from the cubic B/sub 1/ structure to orthorhombic and trigonal structures, and B/sub 1/-MoN was found to be unstable. To check the reliability of the calculations, we have also calculated the elastic constants for B/sub 1/-NbC and obtained good agreement with experimental results
