Filename: Orbitals (411,503 bytes)
Subj: Atomic Orbitals on Macintosh Date: May 8, 1998
Keywords: Science, Education, Physics, Quantum Mechanics, Orbital, Atom
Abs: This archive contains version 1.0 of Atom in a Box, an educational
program that aids in visualizing the Hydrogenic atomic orbitals, a prime
and otherwise unwieldy example of quantum mechanics. Requires a PowerPC
Macintosh. See
Desc: Unlike other tools in this category, this program raytraces through a
three-dimensional cloud density that represents the wavefunction's
probability density and presents its results in real-time (up to 48 frames
per second on the latest hardware). The user interface is very interactive
and provides a wide degree of flexibility.
It contains all 140 eigenstates up to the n=7 energy level and the allowed
spectral transitions between those eigenstates. It also allows a state
formed by a superposition of up to eight of those eigenstates allowing for
over 3 trillion possible states. The program can display a wavefunction as a
picture of a cloud, use color as phase, plot in red-cyan left/right for 3D
glasses, and slice the wavefunction.
You can download a copy of it and see demonstrations of its output at:
For individual users, this software is US $20 shareware. Once you register,
I'll send you a registration code that eliminates the shareware reminder.
Thank you for your attention,
