Abstract:
A link between the predominant conformer in supersaturated l-glutamic acid aqueous solution detected by FTIR spectroscopy and the polymorphic outcome is reported. In particular, the supersaturation is found to determine the morphology of the initially crystallized α form and thus to affect the rate for its further transformation to the β form.
