Let G be a connected graph. If G contains a vertex v such that G− v is a bicyclic graph, then G is called a quasi-bicyclic graph. Let B n, d¯={G: G is a quasi-bicyclic graph of order n with G− u¯ being bicyclic and d G (u¯)= d¯}. We study structure characteristics of graphs on spectral moments. We also determine the last and the second last quasi-bicyclic graphs, in S-order, among all graphs in B n, d¯, respectively.
