A comment and a question on the heat of vaporization:
While the paper cited by David Case (Horn, Swope el al. 2004) probably presents the most correct calculation of enthalpy of vaporization,
I believe the “traditional” form without the corrections can be useful in many contexts.
The simple form is ( see for example Jorgensen, Maxwell and Tirado-Rives 1996):
delta H vap = E intra(g) - (E intra(l) + E inter(l)) + RT
Applying all the corrections from the Horn, Swope et al. paper for another solvent than water is probably also not trivial.
Then to my question:
One of the corrections in the TIP4P-Ew model is a long-range LJ correction.
Does Amber 9 include such a energy correction in the energy it outputs?
Sincerely
Eirik da Silva
