Crystal field theory (CFT) describes the breaking of orbital degeneracy in transition metal complexes due to the presence of ligands. Once the ligands' electrons interact with the electrons of the d-orbitals, the electrostatic interactions cause the energy levels of the d-orbital to fluctuate depending... Upon spin-polarization, the total energy lowers by about 0.43 eV, which is paralleled by a strengthening of the Fe—Fe bonds by roughly 5 per cent. The shifts in the majority (red) and minority (blue) spin sublattices have removed the antibonding states at the Fermi level, thereby maximizing the Fe—Fe bonding as far as possible. I am asked to draw an energy level diagram that shows the relationship between the energy quantities involved in the problem. What I did was I calculated the standard enthalpy change of the reaction first (-43.16 kJ/mol-rxn) and then drew the diagram below. Did I draw the diagram correctly?

It seems that I can't wrap my head around the concept of the k-vector and crystal momentum. From my waves course I remember that the wave vector sorta represents where the wave propagates (in an isotropic and homogeneous material). So in solid state that could be thought as the same thing applied to the wave function, right? And here comes the troubles: why and how is it related to the momentum of a particle? I think I get the math behind it but not the concept. Furthermore, given th...
