Scaling and merging crystallography
WebWhen we pointed out the flawed multiplicity dependence of R merge and recommended making resolution cutoff decisions based on precision of the data after merging , we … Webflat and average around 1 when scaling with either merged or unmerged Friedel pairs. On the other hand, if χ2> 1 and you see a clear resolution dependence of the χ2for scaling with merged Friedel pairs (i.e., the χ2increases as the resolution decreases), there is a strong indication of the presence of an

WebThe scaling procedure in iMosflm is not meant for careful scaling and merging; instead, it's supposed to give you a decent idea about the quality of your integration, estimate the correct space group and resolution limits, and inform the next indexing, lattice refinement, or integration approach if necessary. In cases of really nice data ... To synthesize virtual powder patterns from spot-finding results, highly accurate spot positions are required; therefore, the experimental geometry must be measured with high accuracy as well. We achieved this in a two-step process: first, the beam centre and detector distance were determined using powder diffraction … See more Benzeneselenol (97%, 375152), diphenyl ditelluride (98%, 384127), silver (I) oxide (99%, 221163), silver powder (>99.9%, 327077), and thiophenol (97%, T32808) were used as received from Sigma Aldrich.
