What is Tr[quadrupol]?
Posted: Sat Jul 12, 2008 1:58 am
Hello,
When I use LDIPOL=.TRUE. IDIPOL-4 DIPOL=0.5 0.5 0.5 to calculate the dipole moment of an isolated molecule, I see Tr[quadrupol] under the dipolmoment result line in the OUTCAR.
Does Tr[quadrupol] mean quadrupole moment of the molecule? If so, how is it calculated in VASP. Is its uint electrons*Angstrom^2 ?
Thanks
