Let G be a simple graph with n vertices and let A(G) be the (0, 1)-adjacency matrix of G. The characteristic polynomial of the graph G with respect to the adjacency matrix A(G), denoted by χ(G, λ) is a determinant of (λI − A(G)), where I is the identity matrix. Suppose that λ1 ≥ λ2 ≥ ⋯ ≥ λn are the adjacency eigenvalues of G. The spectrum of the graph G, denoted by Spec(G), is the multiset of its adjacency eigenvalues. Unicyclic graph is connected graph containing exactly one cycle. In this paper we determine the spectrum of unicyclic graph containing cycle with length 6.
