Shape Information in the Kappa Values

Brillouin has modified this expression to give the redundancy within the molecule, R-. 

By using the limit-structure model for each order of shape attribute as we have done above, we can quantitate these attributes from their relationships to two extreme structures associated with each model. 

In Table 3, a range of k values is shown for structures ranging from a linear structure to one with a maximum number of cycles. The structural information encoded in k is related to the complexity, or more precisely, the cyclicity of a molecule. All acyclic structures with six atoms would have k - 6.000, or, in general, k = A for acyclic structures. 

In the case of k, the structures and index values in Table 3 for A = 7 reveal that information is encoded relating to the degree of star graph-likeness and 

The information in indexes can be illustrated by the set of structures in Table 3. The values are larger when branching is nonexistent or when it is located at the extremities of a graph. We can say that encodes information about the centrality of branching.
