Dear developers,
The input file of HF/STO-3G calculation of C2H6 is given below.
With and without symmetry, the ordering of atoms in the [Atoms] section of
the Molden file are the same,
but the MO coefficients are different. For example, orbital 1.4 (E =
-0.4566),
without symmetry with symmetry
1 0.00000000000 0.00000000000
...
12 0.33901515512 0.00000000000
13 -0.33901461639 0.33901488579
14 -0.00000053873 -0.33901488579
15 -0.33901461639 -0.33901488579
16 0.33901515512 0.33901488579
It seems the problem is in [Atoms]. The atoms should be reordered as in the
output file.
