Chem. Phys. 115 (2001) 9733). This probably originates in the circumstance that the TD-UDFT results are biorthonormal and Gaussian does not give normalized coefficients in this case.

I have been working with protein homology modeling, but now I a have a=20 protein sequence wich have a very low identity with other proteins = deposited=20 in the PDB and other database (very high e-value, and low score, too). = When=20 I submit my protein to an homology modeling process, the result is very=20 bad... the program returns to a small part of this molecule modeled. So, = I=20 thougth someone can help in another kind of molecular modeling, such ab=20 initio, and as I can solve me protein structure. If you know something about any free program or tool on the internet, it = will be very helpfull to my work. Thank you very much.

Ribeiro. Dear collegue, In his book (p. 419) C. Cramer shows the PMF curve of, say, a dimer of Cl- in water. This dimer is known to display two minimas at large and short distances. The two cavities are the cavities of the two Cl-! At large distance the two cavities are two separated spheres, at some distance they begin to interpenetrate. This is the issue mentioned in Cramer's book.

I thought the PMF curve referred to solute and solvent molecules, not two solute molecules and that is why I could not understand some issues. Now it makes sense to me, I mean a curve of PMF between solute and solvent, in a implicit description of the solvent, would be a decreasing curve just like the potential electrostatic energy curve (as there is no consideration of entropic effects), so there is no way of getting an accurate PMF (solute x solvent) if there are no explicit solvent molecules. -------------------------------------------------------------------------------- > From: owner-chemistry*ccl.net > To: raphaelri*hotmail.com > Subject: CCL: Answer to : PMF with implicit Solvent > Date: Mon, 20 Oct 2008 16:03:45 +0200 > > > Sent to CCL by: Pierre Archirel [pierre.archirel*o*lcp.u-psud.fr] > This is an answer to R.
