Figure 1. Single molecule embedded in a transparent solid. The region enclosed in the circle is called impurity center. Figure 1a. An impurity center consists of one molecule and its closest surrounding Let us consider  the absorption of light by one single molecule embedded in an optically transparent solid. An example of such solid could be a piece of plastic  or polymer material, a chunk of a laser crystal or a piece of simple window glass. The relevant  quantum-mechanical system consists of  the electronic and vibrational degrees of freedom  of the molecule and of the vibrational motion of the surrounding solid. Figure 1 shows a molecule  surrounded by a solid.  The molecule together with its closest neighbors (region inside red circle) is called impurity center. The absorption spectrum of one molecule is called  homogeneous absorption spectrum or homogeneous line shape. Suppose that absorption occurs because of transition  from the ground electronic state  of the impurity center t
