Unicyclic graphs are connected graphs in which the number of edges equals the number of vertices. Let Un,dbe the class of unicyclic graphs of order n and diameter d. For unicyclic graphs, lexicographic ordering by spectral moments (S-order) is discussed in this paper. The last d+⌊d2⌋-2 graphs, in the S-order, among all unicyclic graphs in Un,d(3⩽d⩽n-5) are characterized. In addition, for the cases d=n-4 and d=n-3, the last 2n-11 and last n+⌊n2⌋-7 unicyclic graphs in the set Un,dare also given, respectively.
