Translation-rotation-internal coordinates (TRIC) are created by including translations and rotations in the primitive internal coordinates set coupled with existing delocalization techniques. The initial Hessian in the space of primitive internal coordinates is a diagonal matrix with a few minor adjustments adopted from Schlegel's proposed values. The translations and rotations, and atomic Cartesian coordinates are given force constants of 0.05, bonds and angles involving non-covalent distances are given force constants of 0.1, and dihedral angles have their force constants set to 0.023.
