This method keyword requests a semi-empirical calculation using the CNDO Hamiltonian [Segal66]. No basis set keyword should be specified.
Energies, “analytic” gradients, and numerical frequencies.
The CNDO energy appears in the output file as follows:
SCF Done: E(UCNDO) = -8.08016620373 A.U. after 11 cycles
The energy is as defined by the CNDO model.
