Gaussian 03 Online Manual
Energies, "analytic" gradients, and numerical frequencies. Restricted open shell (RO) wavefunctions are limited to optimizations using the Fletcher-Powell and pseudo-Newton-Raphson methods (the FP and EnOnly options to Opt, respectively).
The MINDO3 energy appears in the output file as follows (followed by the x, y, and z components of the dipole moment):
Energy= -.080309984532 NIter= 10. Dipole moment= .000000 .000000 -.739540
The energy is as defined by this semi-empirical model. Note that energy differences computed from the values in semi-empirical calculations are in Hartrees and may be compared directly with energy differences computed from jobs using other methods.
