WebCGLS refinement can be also usefully employed in the early stages of refinement of medium and large 'small molecules'; it requires more cycles for convergence, but is fast … WebAug 28, 2024 · Powder X-Ray diffraction (XRD) was developed in 1916 by Debye (Figure 7.3.12) and Scherrer (Figure 7.3.13) as a technique that could be applied where traditional single-crystal diffraction cannot be performed. This includes cases where the sample cannot be prepared as a single crystal of sufficient size and quality.
