LetMbe a perfect matching of a graphG. The smallest number of edges whose removal to makeMas the unique perfect matching in the resulting subgraph is called the anti-forcing number ofM. The anti-forcing spectrum ofGis the set of anti-forcing numbers of all perfect matchings inG, denoted by. In this paper, we show that any finite set of positive integers can be the anti-forcing spectrum of a graph. We present two classes of hexagonal systems whose anti-forcing spectra are integer intervals. Finally, we show that determining the anti-forcing number of a perfect matching of a bipartite graph with maximum degree four is a NP-complete problem.
