Requests a semi-empirical calculation using the INDO Hamiltonian [42]. No basis set keyword should be specified.

Energies, "analytic" gradients, and numerical frequencies.

The INDO energy appears in the output file as follows (followed by the x, y, and z components of the dipole moment):

Energy=   -19.034965532835 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.
