Combining X-ray and neutron crystallography with spectroscopy [PDF]

, 2017
X-ray protein crystallography has, through the determination of the three-dimensional structures of enzymes and their complexes, been essential to the understanding of biological chemistry. However, as X-rays are scattered by electrons, the technique has

Molecular structure, DFT studies and UV–Vis absorption of two new linear fused ring chalcones: (E)-1-(anthracen-9-yl)-3-(2-methoxyphenyl)prop-2-en-1-one and (E)-1-(anthracen-9-yl)-3-(3-fluoro-4-methoxyphenyl)prop-2-en-1-one

Acta Crystallographica Section E: Crystallographic Communications, 2018
The title compounds, C24H18O2 and C24H17FO2, were synthesized using the Claisen–Schmidt condensation method and characterized by UV–Vis spectroscopy. Weak intermolecular C—H...O, C—H...π and π–π hydrogen-bonding interactions help to stabilize the crystal
