用太赫兹时域光谱（THz-TDS）测定了L-、D-和dl -酒石酸的吸收光谱。dl -酒石酸及其对映体（L-和d -酒石酸）有不同的吸收带。结果表明，THz-TDS可以用来区分dl -酒石酸和对映体（L-和d -酒石酸）。此外，偏最小二乘法（PLS）可以提高太赫兹- tds法测定L-酒石酸和dl -酒石酸混合物中L-酒石酸的含量。
Absorption spectra of polycrystalline L-, D-, and DL-tartaric acid have been measured by terahertz time domain spectroscopy (THz-TDS). Different absorption bands are observed for DL-tartaric acid and its enantiomers (L- and D-tartaric acid). This result shows that the THz-TDS can be used for distinguishing between DL-tartaric acid and enantiomers (L- and D-tartaric acid). Moreover, partial least square (PLS) can be found to improve the quantitation of L-tartaric acid in L- and DL-tartaric acid mixture by THz-TDS.
