I´m looking for a software that would allow me to test atom interaction acurretly in 3D, with public variables (i.e. customizable parameters) like the pressure and the temperature. I´m looking for something that takes into account S, P, D orbits with their real shape and the real numbers of electrons with their respective charges. Something that can portrait hybridization well, that can show bonding of every kind. I´d like something that´s freeware, but if you know about a good paid app it would be useful to know that too. I´m really hoping this kind of program exists.
