Where can I get a molecule modelling program for chemistry?

Question

I would also like to be able to copy and paste the structural formulae or the actual 3D shapes of the molecules into Microsoft Word. I am an AS Level (year 12) chemistry student, but I have only been studying since the beginning of September. I have (of course) done GCSE chemistry, but I don't want something overly complicated. Free would be nice too! :P

Answer 1

There is ChemDraw, that you can buy

ChemSketch is offered online as freeware or shareware (I forget)

If you want a program that does computational chemistry calculations (DF Theory or Ad Hoc, etc) you might look at buying Spartan.
