HMO (Huckel Molecular Orbital) is an interactive Huckel molecular orbital program created especially for Chem 3001. It is easy to learn, requires minimal input (in particular, the Fock or adjacency matrices are not needed as input) and catches most input errors. HMO calculates MO energies and coefficients, pi-electron populations, bond orders and lengths, free valences, and self polarizabilities for planar, conjugated hydrocarbons.

HMO is invoked by entering hmo at the DOS prompt. Input is typed in response to the program's questions and the results are shown on the monitor. HMO is free for non-commercial use.
