Abstract :
The Harary spectrum of a connected graph G is the collection of the eigenvalues of its Harary matrix. The Harary en ergy of a graph G is the sum of absolute values of its Harary eigen values. Harary equitable partition is defined and is used to obtain Harary spectrum of generalized composition of graphs. Harary equienergetic graphs have been constructed with the help of gen eralized composition through Harary equitable partition.
