We first compute the spectrum of this graph for several classes of finite groups, in particular AC-groups. We show that the commuting graphs of finite non-abelian AC-groups are integral. We also show that the commuting graph of a finite non-abelian group G is integral if G is not isomorphic to the symmetric group of degree 4 and the commuting graph of G is planar. Further, it is shown that the commuting graph of G is integral if its commuting graph is toroidal.</p>}, number={1}, journal={MATEMATIKA: Malaysian Journal of Industrial and Applied Mathematics}, author={Nath, Rajat Kanti and Dutta, Jutirekha}, year={2017}, month={Sep.}, pages={87–95} }
