Force field

Parameters

ff94

ff96

ff98

ff99

Param99 was developed for organic and biological molecules using the restrained electrostatic potential (RESP) approach to derive the partial charges:

ff02

The ff02 force field is a polarisable variant of ff99. The charges were determined at the B3LYP/cc- pVTZ//HF/6-31g* level, and hence are more like "gas-phase" charges.
