This is the default for all calculations using the ZIndo method. No orbitals are printed, and no population analysis is done. Multipole moments: dipole through hexadecapole.ĪPT charges are also computed by default during vibrational frequency calculations. The total charge per fragment is also reported if applicable. By default, all orbitals are included, but the output can be limited to a specific orbital range with the Orbital option.Ītomic charge distribution. Output controlled by the Pop keyword includes: Population analysis results are given in the standard orientation. If several combinations are of interest, additional jobs steps can be added by specifying Guess=Only Density=Check, to avoid repeating any costly calculations.

Note that only one density and method of charge fitting can be used in a job step.

The density that is used for the population analysis is controlled by the Density keyword. Note that the Population keyword requires an option. Populations are done once for single-point calculations and at the first and last points of geometry optimizations. The default is to print just the total atomic charges and orbital energies, except for Guess=Only jobs, for which the default is Pop=Full (see below). This properties keyword controls printing of molecular orbitals and several types of population analysis and atomic charge assignments. G09 Keyword: Population Population DESCRIPTION
