Is there any way to generate the initial = > files for single amino acids from Amber force field? IMHO no, or better: not that easy. Remenber that the Amber program was designed to treat proteins not single amino acids. Of course, you could setup a new residue, that resembles the geometry and charges of a single amino acid, but you'd have to create extra library files for that; then you could select whether you wanted the zwitterionic or the neutral form. However, you should post that question on the Amber mailing list (check it's archives first), as there might be a better solution, or someone has already setup the parameter files.

The weather in Central Ohio is quite severe (very strong winds) and many houses are without electricity due to downed power lines. A few hours ago power went down in my home ("the home of CCL" {:-|}). I learned that the transformer blew up, so I powered down the CCL server that was on UPS. Now the power is back but who knows for how long. The network is also unstable. If you had sent a message to CCL and it was not distributed, please ask me to look into it or resend it. Sorry, but I really cannot do anything about the acts of nature... So do not be surprised if CCL goes down again in the near future... It is blowing really good...

Actually, your system had **NO** spin contamination - notice that the numbers before and after gaussian tries to eliminate spin contaminations are the same. Those numbers are *NOT* spin contamination per se, but the expectation valule of the S^2 operator, which for a siglet is exactly 0.75. What you are seeing there is rather some SCF convergence failure. Try adding a "P" as the first thing in your route card, to tell Gaussan to generate extra information about the SCF procedure, like for example: #P B3LYP/cc-pVTZ blah blah blah... ^^^^ HTH Gustavo.

A succinct statement of scientific purpose is "If you can't measure it, it is just your opinion." Modelers provide "measurements" (whether statistical, static, or through dynamic simulation) ... or do these count as "measurement"? In the early 90's, computational toxicology was impeded in teh ag chem industry by a US regulatory requirement that -all- adverse environmental events be disclosed. Some corporations would not do any modeling in this area, since it was not known whether the result of a simulation by a validated method would be considered a reportable "event". I realize that many people will classify regulatory agencies with charlatans, but these philosophical issues do impinge on how perceive our discipline and we do our jobs. -Steve > Eric Scerri wrote: > >>Sodium a poisonous metal combines with chlorine, a greenish poisonous gas, >>to yield something that is not only non-poisonous but essential for life - NaCl. >>... > > > Hope that most people don't confuse Na and Na+ or Cl2 with Cl-, etc. > I leave associated philosophical discussions for homeopaths, charlatans, ... > > Michel Petitjean, Email: petitjean=-=itodys.jussieu.fr > ITODYS (CNRS, UMR 7086) ptitjean=-=ccr.jussieu.fr > 1 rue Guy de la Brosse Phone: +33 (0)1 44 27 48 57 > 75005 Paris, France.

The statement is true, of course, if you're talking about the multi-photon ionization spectrum, as Phil was (J. Chem. Phys. 64, 4143-4148 (1976)... Which just goes to show that what we colloquially refer to as "properties" are often context-dependent and environment-dependent. As we all know and acknowledge, the properties of an atom in a molecule ("sodium" or "chlorine" in NaCl or "hydrogen" or "oxygen" in water) depend upon its bonding environment; the properties of a molecule in vitro depend on the solvent and other conditions. Can the properties of water be predicted from those of "hydrogen" and "oxygen"? Yes, to a good approximation, as long we associate these atom types with the corresponding virial fragments in the bonding environment found in water (rather than with those in H-H and O=O). Dr. N.
