  InteGriTy is a software package that performs topological analysis following
AIM approach on electron densities given on 3D grids. Use of tricubic
interpolation is made to get the density, its gradient and hessian matrix at
any required position. Critical points and integrated atomic properties have
been derived from theoretical densities calculated for the compounds NaCl and
TTF-2,5Cl2BQ, thus covering the different kinds of chemical bonds: ionic,
covalent, hydrogen bonds and other intermolecular contacts.
