Twinned <scp>L</scp> -aspartic acid

By improving the data quality with appropriate twin handling in the intensity integration, difference-Fourier maps show indications for asymmetric double-well hydrogen bonds between the carboxylate groups of the title molecule. Refinements with spherical scattering factors (IAM) and with non-spherical scattering factors (NoSpherA2) are consistent with this observation.

Abstract

By improving the data quality with appropriate twin handling in the intensity integration, difference-Fourier maps show indications for asymmetric double-well hydrogen bonds between the carboxylate groups of the title molecule. Refinements with spherical scattering factors (IAM) and with non-spherical scattering factors (NoSpherA2) are consistent with this observation.
