This guided-inquiry, upper-division undergraduate organic lab experiment, a hybrid of problem-based learning (PBL); process-oriented, guided-inquiry learning (POGIL); and peer-led team learning (PLTL) has been developed to ease the transition from the undergraduate lab to a research lab environment. The characterization of a mixture of camphor and p-coumaric acid involves a complex separation as well as thoughtful NMR experiments and solvent selection. Technique and problem-solving instruction (involving thin-layer and column chromatography as well as 1D [coupling constant analysis] and 2D [COSY, HSQC, and HMBC] NMR spectroscopy) has been simplified for the instructor by the development of videos, detailed notes, and assignment worksheets.

克服从本科生实验室到研究实验室的障碍：上级本科生有机实验室中复杂混合物的引导查询结构表征

这是一个指导性的，探究式的本科有机实验室实验，是基于问题的学习（PBL）的混合体；面向过程的，引导式的探究式学习（POGIL）；并开发了由同伴主导的团队学习（PLTL），以简化从本科生实验室到研究实验室环境的过渡。樟脑和对-香豆酸混合物的表征涉及复杂的分离以及深思熟虑的NMR实验和溶剂选择。通过开发视频，为讲师简化了技术和解决问题的说明（涉及薄层色谱和柱色谱以及一维[偶联常数分析]和二维[COSY，HSQC和HMBC] NMR光谱）以及分配工作表。
