CCL: symmetry in molpro



 Sent to CCL by: "Peterson, Kirk" [kipeters\a/wsu.edu]
 Dear Pierre,
 I'm not sure why the first syntax doesn't work, but in the 2nd case you need to
 add your extra electron
 to your total number of electrons, i.e., if your molecule really does have a
 negative charge then the total
 number of electrons is 86, not 85, i.e.,   wf,86,1,1
 best regards,
 -Kirk
