ModesLab Program

It calculates several families of molecular descriptors such as the spectral moments of the bond adjacency matrix,  the atom (vertex)- and bond (edge)-based connectivity indices, classical topological descriptors (e.g., Balaban, Harary, Kier shape indices, etc.), topographic indices, physicochemical properties, and quantum chemical descriptors. MODESLAB v1.5 is free of charge for academic use.
