英文摘要	NSFC [10671162]; Program of 985 Innovation Engineering on Information in Xiamen University; The general Randic index R(alpha)(G) is the sum of the weights (d(G)(u)d(G)(v))(alpha) over all edges uv of a (molecular) graph G, where alpha is a real number and dGM is the degree of the vertex u of G. In this paper, for any real number alpha <= -1, the minimum general Randic index R(alpha)(T) among all the conjugated trees (trees with a Kekule structure) is determined and the corresponding extremal conjugated trees are characterized. These trees are also extremal over all the conjugated chemical trees. (C) 2008 Elsevier B.V. All rights reserved.
