摘要：
Single crystals of triglycine sulfate (TGS) were grown from solutions containing 10 mol% of L-alpha-alanine, DL-alpha-alanine, sarcosine, L-serine or L-valine. The crystal form, domain structure and internal bias field E(b) of these crystals were investigated. The crystal form and macroscopic distribution of E(b) in crystals doped with L-alpha-alanine and L-serine show polar symmetry 2, and those in crystals with DL-alpha-alanine and sarcosine show the centrosymmetric 2/m. The molecule of L-valine cannot be incorporated in TGS crystal.
