Initial Comment:
Hey great Job,just wondering whether or not retron/synthon identification was 
possible with jmol.How far does jmol go with respect to 
inorganic/organometallics,what elements can I model in jmol? Can anyone suggest 
a good particle in a box program besides hyperchem for my  students?
  I have started modifying jmol to do it for polyenes,got as far as the 1d box 
being half the number of double bonds,how would I go about integrating a box 
parallel to the polyene and associated energy levels? I am using the graphic 
that links atoms as the boundaries of the box,still working on integrating the 
calculator.
 I'll create an account and post when I'm through.

dear anon,

Sounds like a nifty application you are working on. Please be aware of the
lesser GNU license -- that any modification you make to Jmol must become
publicly available. The typical way this is done is to start a branch and
do all the modications there, using Eclipse to update it. This is very
generally useful, because then when you get stuck you can refer to that
branch, and other programmers can test and provide advice.

I assume you are working with Jmol 11.7 in this? It would not be advisable
starting with 11.6, which is now many subversions behind 11.7. 

In answer to your questions:

retron/synthon -- you can use the functionality of Jmol to develop this. I
don't think anything particular would be necessary for any changes to Jmol
itself. It's all valence/connection based, and that is all easily
determined using methods already in place.

elements/modeling -- they are all there; the only aspect Jmol "models" is
that it does incorporate the Universal Force Field, which was specifically
designed by the Goddard group to encompass organometallic and inorganic
compounds.

Actually, rereading what you have there, I would highly recommend not
modifying Jmol. The web-based interface is so extensive, why not just
consider this a web page development project? It would be far more
accessible, you would have a much greater audience, and it wouldn't require
any Java programming. 

Not trying to be insensitive here, but surely simple 1d particle-in-a-box
applets are out there. No? It's sort of a classic example system. I know
the temptation to "do it yourself" but, for example, see
http://www.falstad.com/mathphysics.html -- why involve Jmol?
