# A relativistic geometry optimization with the ZORA formalism. Both a scalar
# relativistic geometry optimization, as well as a spin-orbit coupled
# relativistic geometry optimization are performed. Spin-orbit effects on the
# geometry are often not so large for closed shell molecules, but takes
# typically a factor 4 times as much as a scalar relativistic calculation.
