title: Polymorphism in acesulfame sweetener: structure-property and stability relationships of bending and brittle crystals.
abstract: Acesulfame is found to exist in two crystalline forms of which Form I (needles) shows bending upon mechanical stress. Crystal structures explain their mechanical response. This is the first case of aliphatic organic compounds featuring a bending phenomenon. Form I is physically more stable than Form II in ambient conditions.
