Re: D4d symmetry in GAMESS

Alex Granovsky


dihedral groups like Dnd are a bit tricky. The correct input file is as follows:

Dnd       4

LITHIUM     3.0      0.607522059        -1.466687995        -2.116708996

I have also attached a sample picture showing that X and Y axes
direction is along C2 axes and this why your input file was
not correct.

Kind regards,
Alex Granovsky
