AmberEHT Forcefield: Novel Approaches to Small Molecule Parameterization
A new methodology to determine bonded forcefield parameters is presented. A coordinate-free Hückel calculation is the basis for chemical perception and the results are used in combination with physical chemistry relationships to determine parameters for bond lengths, angles, and torsions (with associated force constants). Comparisons to quantum mechanical torsion profiles are presented to validate the resulting parameterizations.
