Abstract

Chiral symmetry breaking in stirredcrystallization of sodium chlorate (NaClO3) is believedto occur via nucleation of
a single chiral ‘‘mother crystal’’ that produces a new generation of crystals which inherit its chirality. We here report
results of stirredcrystallizations resulting in massive ‘‘instantaneous’’ primary nucleation and total symmetry breaking.
The results of these experiments suggest that the current explanation for chiral symmetry breaking via nucleation of a
single ‘‘mother crystal’’ is not adequate and that the mechanism to explain the chiral symmetry breaking in
crystallization remains as an open question.
