An augmented reality application (H NMR MoleculAR) and worksheet have been developed as part of a first-semester Organic Chemistry II laboratory to help students visualize the concepts involved when problem solving with 1H NMR spectroscopy. This activity was designed to encourage conceptual problem-solving and prevent memorization by eliminating the use of chemical shift tables. The augmented reality models aid students in visualizing 3D structures, molecular orbitals, and electrostatic potential maps. The worksheet uses the compare-predict-observe-explain (CPOE) framework so students can abstract principles about how proton equivalency, electronegativity, and anisotropy impact the number, intensity, splitting, and shift of signals on a spectrum. Student user experience and classroom observations will be discussed to evaluate the application.
