摘要：

Application of a technique developed for in situ solid-state (13)C NMR studies of crystallization processes reveals direct evidence that crystallization of glycine from a methanol/water solution involves the initial transient formation of the beta polymorph, which then undergoes a solution-mediated polymorphic transformation to yield the more stable alpha polymorph.
