In the slow modulation regime, we can find Q(T) using random walk theory and compare it with the exact result obtained in Appendix C. In this regime, the molecule can be found either in the up ( + ) or in the down (—) state, if the transition times [i.e., typically <9(1/R)] between these two states are long the rate of photon emission in these two states is determined by the stationary solution of the time-independent Bloch equation in the limit... 

The important term electronic band structure is identical with the course of the energy of an extended wave function as a function of k, and we seek for E ip k,r)), the crystal s equivalent to a molecular orbital diagram. As stated before, the fc-dependent wave function ip k,r) is called a crystal orbital, and there may be many one-electron wave functions per k, just as there may be several molecular orbitals per molecule. Due to the existence of these periodic wave functions, there results stationary states in which the electrons are travelling from atom to atom the Bloch theorem thereby explains why the periodic potential is compatible with the fact that the conduction electrons do not bounce against the ionic cores. 

Next, one constructs stationary states with quasi-momentum Kin Bloch-function form ...
