Electronic Charge Distribution

In this work, experimental and data analysis procedures were developed and applied for studying amino acid crystals by means of X-ray phase measurements. The results clearly demonstrated the sensitivity of invariant triplet phases to electronic charge distribution in D-alanine crystals, providing useful information for molecular dynamics studies of intermolecular forces. The feasibility of using phase measurements to investigate radiation damage mechanisms is also discussed on experimental and theoretical grounds.

A strong asymmetry in the electronic charge distribution on the central metal of Re2O7 is caused by bridging oxygen atoms. This asymmetry is measured by determining the 185Re, 187Re-NQR transitions, NQR coupling constants and asymmetry parameter.
