This program is an IBM-PC FORTRAN version of the Pariser-Parr-Pople Molecular Orbital (PPP-MO) method. It is useful for the prediction of color properties of organic molecules with conjugated PI systems. Wavelength of the maximum absorption of the visible band, absorption band intensity, and polarization direction of the absorption band, along with MO energies, electron density and bond order, represent some of the information obtainable by this method. A detailed review of the method and its uses are found in the program documentation. FORTRAN 77 (Microsoft 3.2) Lines of Code: 1050 |
