WebThe Flack parameter is calculated during the structural refinement using the equation given below: where x is the Flack parameter, I is the square of the scaled observed structure factor and F is the calculated structure factor. By determining x for all data, x is usually found to be between 0 and 1. If the value is near 0, with a small ... WebA value of the Flack parameter that deviates significantly from zero (taking into account the associated s.u.) might indicate that the absolute structure should be inverted in case of a value closer to 1.0 than to zero. A value close to 0.5 may be indicative of an inversion twin or a missed centre of inversion.
WebDefinition The Flack parameter is the molar fraction in the defining equation , where represents an oriented two-domain-structure crystal, twinned by inversion, consisting of an oriented domain structure and an oriented inverted domain structure . In reciprocal space, the Flack parameter is defined by the structure-amplitude equation .
