Advancements in organic chemistry depend upon chemists’ ability to interpret NMR spectra, though research demonstrates that cultivating such proficiency requires years of graduate-level study. The organic chemistry community thus needs insight into how this expertise develops to expedite learning among its newest members. This study investigated undergraduate and doctoral chemistry students’ understanding and information processing during the interpretation of 1H NMR spectra and complementary IR spectra. Eighteen undergraduate and seven doctoral chemistry students evaluated the outcome of a series of syntheses using spectra corresponding to the products. Eye movements were measured to identify differences in cognitive processes between undergraduate and doctoral participants, and interviews were conducted to elucidate the chemical assumptions that guided participants’ reasoning. Results suggest five areas of understanding are necessary for interpreting spectra, and progress in understanding corresponds to increasing knowledge of experimental and implicit chemical variables. Undergraduate participants exhibited uninformed bidirectional processing of all information, whereas doctoral participants exhibited informed unidirectional processing of relevant information. These findings imply the community can support novices’ development of expertise by cultivating relevant understanding and encouraging use of informed interpretation strategies, including preliminary evaluation of relevant variables, prediction of expected spectral features, and search for complementary data across spectra.

发展1 H NMR光谱解释的专业知识
有机化学的进步取决于化学家解释NMR光谱的能力，尽管研究表明培养这种能力需要多年的研究生水平研究。因此，有机化学界需要了解这种专业知识如何发展，以加快其最新成员之间的学习。本研究调查了本科生和博士化学专业学生对1的解释过程中的理解和信息处理1 H NMR光谱和互补的IR光谱。18名本科生和7名博士化学专业学生使用与产品相对应的光谱评估了一系列合成的结果。测量眼动以识别大学生和博士生在认知过程上的差异，并进行访谈以阐明指导参与者推理的化学假设。结果表明，对光谱进行解释需要理解的五个领域，而理解的进步对应于对实验和隐式化学变量的认识的增加。本科生表现出对所有信息的非知情双向处理，而博士生表现出对相关信息的知情单向处理。
