A molecule of TPA, C8H6O4, showing the connectivity and atom numbering used in the z-matrix in Table 1[link]. The two internal degrees of freedom are denoted [\phi _{i}] and the dummy atom at the centre of symmetry is number 1 (`x1'). The dotted line shows an example of an intramolecular non-bonded contact.
