Symmetric vectors attributable to each of the irreducible representations are determined by subtraction of the "symmetrized" molecule with the symmetry operations defined by one row of an expanded point group table (i.e., without grouping of equivalent operations), from the cokernel symmetric representation -the totally symmetric representation of the class in most cases. The totally symmetric query component (Ag, A1, A1g, etc.) is compared to the model to attain an indication of the totally symmetric distortion, equal to zero when no model is used.
