Q-Chem can output a file suitable for analysis with the Atoms in Molecules package (AIMPAC). The source for AIMPAC can be freely downloaded from the web site
http://www.chemistry.mcmaster.ca/aimpac/imagemap/imagemap.htm
Users should check this site for further information about installing and running AIMPAC. The AIMPAC input file is created by specifying a filename for the WRITE_WFN $rem.
WRITE_WFN
WRITE_WFN
Specifies whether or not a .wfn file is created, which is suitable for use with
AIMPAC. Note that the output to this file is currently limited to f orbitals,
which is the highest angular momentum implemented in AIMPAC.
TYPE:
STRING
DEFAULT:
(NULL)
No output file is created.
OPTIONS:
filename
Specifies the output file name. The suffix .wfn will
be appended to this name.
