In this section we will first consider the configurational coordinate diagram 4,7) that describes the interaction of an optical center with its surroundings in the absence of center-center interaction. Later we will deal with the interaction between two centers that results in energy transfer (4,8). 

The development of the quantum field theory so far has been cast in a form most directly suited for applications in which the material part of the system comprises only those molecules or optical centers involved in the interactions of interest, with no other matter present. More generally in condensed-phase materials, such centers are surrounded by other atoms or molecules whose electronic properties modify the fields experienced (and produced) by those optical centers. To take account of such influences, we introduce the microscopic displacement electric field d. This arises as a direct consequence of working within the multipolar...
