The energy of a molecular graph G is defined as the sum of the absolute values of the eigenvalues of A ( G ), where A ( G ) is the adjacency matrix of this graph. This article characterizes conjugated chemical trees with prescribed diameter and minimal energies and presents explicit expressions of their Hosoya indices. © 2006 Wiley Periodicals, Inc.
