摘要: We have measured terahertz and powder x-ray diffraction spectra of D-histidine, L-histidine, DL-histidine. The as-received D L material exists in two different polymorphs: D-histidine is the metastable monoclinic form, while L-histidine stable orthorhombic form. For both enantiomers, recrystallization results a mixture forms.
