Amplified eccentric connectivity index of graphs

A new distance based graphical index, coined as amplified eccentric connectivity index, has been established and the formulae to calculate the amplified eccentric connectivity index of some standard graphs, Dutch windmill graph and molecular graph of cycloalkenes has been computed. Also, in the case of boiling points of primary and secondary amines, the study shows that the amplified eccentric connectivity index gives a greater correlation of 98%, when compared to the Wiener and Eccentric connectivity indices.
