XPAD X-ray hybrid pixel detector for charge density quality diffracted intensities on laboratory equipment

It is shown that high-resolution X-ray diffraction data collection with a laboratory diffractometer equipped with a hybrid pixel detector gives excellent quality structure-factor amplitudes for charge density analysis.

Charge-density analysis using multipolar atom and spherical charge models: 2-methyl-1,3-cyclopent­anedione, a compound displaying a resonance-assisted hydrogen bond

The electron density of 2-methyl-1,3-cyclopentanedione was refined versus synchrotron ultra-high-resolution data using a multipolar model and a virtual and real spherical atoms model. The electrostatic properties were analyzed.
