Some calculations of 1 J (SiC) and 1 J (SiF) are performed by self‐consistent perturbation theory employing standard INDO parameters. 1 J (SiC) is dominated by the contact interaction, whereas the opposite sign for 1 J (SiF) is due to a large orbital interaction. The 1 J (SiC) data are satisfactorily reproduced by calculations employing an sp basis set, whereas the inclusion of silicon 3d orbitals provides a more reasonable account of 1 J (SiF).
