中文摘要：

在这份报纸，我们在 0.32.5 THz 的一个范围上使用了兆兆赫时间域光谱学(THz-TDS ) 调查形成固态氨基酸的 cocrystals，由磨氨基酸的二种不同类型的混合物形成了。为比较，我们准备了双层的样品，由没有磨擦，一起压二个单个部件的小团联合了。在地面混合样品，一些额外的吸收山峰出现了，与特征不同纯部件的山峰，而是这些山峰没出现在双层的样品。因此，在 THz 范围的这些额外的吸收山峰是 cocrystals 的唯一的特征。从我们的结果，我们相信 THz-TDS 是一种有希望的技术描绘 cocrystals。

英文摘要：

In this paper, we used terahertz time-domain spectroscopy （THz-TDS） over a range of 0.3-2.5 THz to investigate the formation of solid-state cocrystals of amino acids, formed by grinding mixtures of two different kinds of amino acids. For comparison, we prepared dual-layer samples, combined by pressing two single-component pellets together without grinding. In the ground-mixture samples, some extra absorption peaks appeared, different from the characteristic peaks of the pure components, but these peaks did not appear in the dual-layer samples. Thus, these extra absorption peaks in the THz range are unique features of cocrystals. From our results, we believe that THz-TDS is a promising technique to characterize cocrystals.
