however, now that monomers can be connected on the same polymers, these 'rings' can include polymer segments. One interaction can be between monomers s and s , while the other interaction can be between a different pair of monomers s and s ; this comes from the term consisting of products of two f -bonds. Conversely, it is also possible that s = s" and s = s , which comes from the single f -bond factors. We indicate the possibility of having connections between dissimilar monomer sites in diagrams by including ω-bonds that indicate correlations between spatially distinct sites, which we denote with orange lines. For the ring expansion, we represent this as:
