CFF force field

CFF (consistent force-field, formerly CFF95) is a member of the consistent family of force fields (CFF91, PCFF, CFF and COMPASS), which are closely related second-generation force fields. They were parameterized against a wide range of experimental observables for organic compounds containing H, C, N, O, S, P, halogen atoms and ions, alkali metal cations, and several biochemically important divalent metal cations. CFF was parameterized for additional functional groups beyond CFF91. It is recommended for all life sciences applications and for organic polymers such as polycarbonates and polysaccharides.
