Gibbs and Helmontz Free Energy

[Teodorico Ramalho <teo_at_epq.ime.eb.br>]

 Dear CCl 's
 I Have used the SCAAS (Surface Constraint All-Atom Solvent) model to
 calculate the Free energy of solvation through FDTI model in InsightII
 program. This mean that I use an ensemble (NVT). The values obtained
 are
 either Helmotz or Gibbs free energy ? I guess,  the values should be of
 Helmontz free energy. Could I to compare my results with experimental
 data (free energy of Gibbs). In other way, which would it be correction
 factor?
 Could anyone help me about this?
 Thanks very much,
 Teodorico
