In this work we show that the underlying structure of some graph theoretical invariants used to describe molecular structure, is the vector space Q(fi, 6) over the field Q of the rational numbers. On a<fi, 6) we define a symmetric bilinear form and then proceed to use the Gram-Schmidt orthogonalizat
