Calculation Of NMR Chemical Shifts

Calculation of NMR chemical shifts (or to be more accurate NMR chemical shielding tensors) are requested via the keyword

PROP=NMR

Use of gauge-including atomic orbitals (GIAOs) to ensure gauge-origin-independent results in such calculations is the default choice. Calculations without GIAOs cannot be recommended except for testing; such calculations are possible via the additional keyword GIAO=OFF.
