✦ Synopsis
Paired series of strongly subspectral molecular graphs which possess a preponderance of common eigenvalues can be constructed by successive attachment of Ž . specific aufbau units repeated subgraphs to certain seed graphs. Recursion relations for the characteristic polynomials of such series are identical and differ only in the input of initial characteristic polynomials. A new operator method for the derivation of recursion relations for singly connected polymeric series is presented. Strongly subspectral series devolve to the same infinite-limit member and density of states, and two types of end-group effects are demonstrated.
