Hi guys,

I used Gaussian W16 to geometry optimization of a two-same-molecule system.

Then, I visualized HOMO and LUMO orbitals of the system with Gaussian View, but HOMO and LLUMO orbitals appeared on only one of the two molecules.

I don't think it is correct because they are same molecules, therefore the orbitals should be symmetric.

I think something was wrong when I visualized the orbitals. Please help me with this.

Attached files are the gjf and the captured photos of HOMO and LUMO.
