ORCA atomic charges

Post by jwk »

The WebMO Results page displays Loewdin atomic charges for ORCA molecular energy calculations, whereas Mulliken charges are displayed for Gaussian, Gamess, and NWChem molecular energy calculations. The Mulliken charges actually do appear in ORCA's output: they are just above the table with the Loewdin charges.

Yes, this should probably be changed for consistency.

How might one edit the parse_orca.cgi file to recover Mulliken charges rather than Loewdin charges?

In parse_orca.cgi (WebMO 23) changing "LOEWDIN" to "MULLIKEN" in line 278 gives the Mulliken charges in the Partial Charge table with the correct atom numbers. However, an extra line labeled "1" is seen at the bottom of the table, and the link to the ViewPartialCharge_mulliken() Javascript is broken, and the graphic spheres on the atoms do not appear.
