Hi,
You need to do some reading on thermodynamics.
The enthalpy and entropy are derivatives of the free energy,
so the answer is no.
For large systems the most efficient way to do it is to also determine
the free energy at a lower and/or higher temperature.
For small systems one can directly determine the enthalpy from
a long simulation, see for instance:

> Hello everyone,
> I'm calculating the relative free energy of binding of DNA bases on a

> My question is, is there a way to extract the relative enthalpy and
