High‐pressure Nucleation of Low‐Density Polymorphs [PDF]

open access: yes, 2020
The crystallized above 0.3 GPa polymorphs β and γ of bis-3-nitrophenyl disulphide, are less dense than the ambient-pressure polymorph α. This high-entropy nucleation illustrates the molecular-scale mechanism of empirical Ostwald’s rule of stages.
