Comparison of silver and molybdenum microfocus X-ray sources for single-crystal structure determination

Journal of Applied Crystallography, 2015
A detailed comparison of single-crystal diffraction data collected with Ag Kα and Mo Kα microsources (IµS) indicates that the Ag Kα data are better when absorption is significant. Empirical corrections intended to correct for absorption also correct well
