In a 1SCF calculation gradients are not calculated by default: in
non-variationally optimized systems this could take a lot of time.
GRADIENTS allows the gradients, in kcal.(Å.mol)-1, to be calculated. Normally, gradients
will not be printed if the gradient norm is less than 2.0. However, if
GRADIENTS is present, then the gradient norm and the gradients will
unconditionally be printed. Abbreviation: GRAD.
