routinely used to parametrize physicochemical effects while investigating reaction mechanisms. In this Communication, we describe an alternate application for LFERs: training sets for model building in an analytical application. In this study, the sterics, quantified by Charton parameters (Δv), of nine secondary chiral alcohol analytes were correlated to the circular dichroism output from a chiral alcohol
线性自由能关系 (LFER) 参数通常用于在研究反应机制时对物理化学效应进行参数化。在本通讯中,我们描述了 LFER 的替代应用程序:用于分析应用程序中模型构建的训练集。在本研究中,九种二级手性醇分析物的由 Charton 参数 (Δv) 量化的空间与手性醇光学传感器的圆二色性输出相关。为了测试模型的有效性,在没有校准曲线的先验知识的情况下,应用相关线性模型来确定两种醇样品的对映体过量。这种方法的误差与以前的实验方法的误差相当(<5%)。
