LUMO
The lowest unoccupied molecular orbitals (LUMO) is the next orbital
above the HOMO; The LUMO is higher in energy. If an electron is pushed
from the HOMO into the LUMO, it is considered to be excited.
The figure to the right is the lowest unoccupied molecular orbital for F2-.
Dipole moments
For the 6-31G basis set: DX = -0.000000
DY = -0.000000
DZ = 0.000000 /D/ = 0.000000 (DEBYE)
For the CCD basis set: DX = 0.000000
DY = -0.000000
DZ = -0.000000
/D/ = 0.000000 (DEBYE)
For the CCT basis set: DX = 0.000000
DY = -0.000000
DZ = -0.000000
/D/ = 0.000000 (DEBYE)
F2- will not have a dipole moment since they are the same two atoms.
