Abstract It is well known that certain compounds, such as long chain fatty acids, can form monomolecular films on water and that the areas of such films can be related to the dimensions of the molecules. Certain polymeric substances, including cellulose derivatives, proteins and the polymer of ω-hydroxydecanoic acid likewise form stable films whose areas can be conveniently measured. At this time we wish to report that we have prepared films of some rubberlike polymers as well, and that the results appear to give useful information about their molecular structures, particularly in relation to branching.

The Estrada index EE is a recently proposed molecular structure-descriptor, used in the modeling of certain features of the 3D structure of organic molecules, in particular of the degree of folding of proteins and other long-chain biopolymers. The Estrada index is computed from the spectrum of the molecular graph. Therefore, finding its relation with the spectral radius r (= the greatest graph eigenvalue) is of interest, especially because the structure-dependency of r is relatively well understood. In this work, the basic characteristics of the relation between EE and r, which turned out to be much more complicated than initially anticipated, was determined.
