**Atomic
Surfaces.mcd** (pdf) |
Generates and displays atomic surfaces based on the Miller indices
for body-centered-cubic (bcc) and face-centered-cubic (fcc) packing
arrangements. Outputs the atomic coordinates to a file. |

**BlackBody.mcd** (pdf) |
Visualization of the blackbody spectrum and the ability to integrate
the spectrum between any two points. |

**Brownian
Motion.mcd** |
Visualization of 1D, 2D, and 3D brownian motion. This
file includes sample avi movies. |

**Diatomic
PESs.zip** |
MathCad program and data files for several diatomic molecules. The
program plots the electronic states (as Morse potentials) for all the
known states with anharmonic constants. |

**Harmonic
Oscillator.mcd** (pdf) |
Analytical solution to the Schrödinger equation with the
harmonic oscillator potential. For two potentials with user-specified
constants (mass, r_{e}, w_{e}), this program plots
the potential, wavefunctions, and determines the overlap integral.
See also **Morse.mcd**. |

**LS
Coupling.mcd** (pdf) |
(Russel-Saunders coupling) Determines the diatomic state
configurations for all possible arrangements of *n* electrons in *m*
orbitals assuming strong coupling between the orbital and spin
angular momentum. |

**Maxwell
Boltzmann.mcd** (pdf) |
The Maxwell-Boltzmann distribution of speeds. |

**Morse.mcd** (pdf) |
Analytical solution to the Schrödinger equation with the Morse
potential. For two potentials with user-specified constants (mass, r_{e},
w_{e}, w_{e}x_{e}), this program plots the
potential, wavefunctions, and determines the overlap integral. See
also **Harmonic
Oscillator.mcd**. |

**Wavelength
Uncertainty.mcd** (pdf) |
The magnitude of the Heisenberg uncertainty principle at short times.
Units of wavelength, wavenumber, frequency, etc. |
