WebThe crystal field theory (CFT) was developed for crystalline solids by the physicist Hans Bethe in 1929. The model takes into account the distance separating the positively and negatively charged ions and treats the ions simply as point charges with the attractive and repulsive interactions between them as purely electrostatic/ionic ones. WebThis deviation from crystal field theory highlights the weakness of crystal field theory's assumption of purely ionic bonds between metal and ligand. The order of the spectrochemical series can be derived from the understanding that ligands are frequently classified by their donor or acceptor abilities.
