Student engagement in evidence-based argumentation plays a central role in science education. These skills can be developed when identifying organic molecules from the spectroscopic data. Molecular structural analysis fosters deep procedural knowledge, as it involves (i) flexibly applying a set of procedures to extract information from spectra,…

Raman spectroscopy, a powerful vibrational spectroscopic technique widely used in chemistry, materials science, and environmental analysis, provides critical molecular insights through spectral fingerprints. However, undergraduate students often lack proficiency in optimizing experimental parameters, interpreting vibrational modes, and applying…

This work presents a modernized lab module for nitrite analysis using a novel probe, AAC (4-(2-aminophenyl)-7-(diethylamino)-2H-chromen-2-one, C[subscript 19]H[subscript 20]N[subscript 2]O[subscript 2]), offering a safer and more sensitive alternative derived from recent research. The 12-h module follows a three-stage structure (Basic…

Ferrocene is an organometallic compound widely incorporated into undergraduate organic and inorganic chemistry curricula. Traditional laboratory experiments typically involve the Friedel-Crafts acylation of ferrocene to produce acetylferrocene or diacetylferrocene, with a purification method focused on column chromatography. To expand the…

The ability to elucidate the structure of organic compounds from their nuclear magnetic resonance (NMR), infrared (IR), and mass spectrometry (MS) spectra is an essential skill, particularly for those engaged in the fields of synthetic and analytical organic chemistry. Spectral analysis constitutes a fundamental component of the curriculum for all…

NMR prediction using ChemDoodle, NMR calculation with Gaussian, and hands-on data collection using a benchtop NMR spectrometer were explored to assess their synergistic capacity in teaching NMR to organic chemistry students. Nine molecules representing functional groups commonly encountered in undergraduate organic chemistry were selected. Spectra…

This study reports an undergraduate laboratory experiment that explores the temperature-dependent kinetics of caffeine release during tea steeping by using quantitative [superscript 1]H NMR spectroscopy with a water suppression pulse sequence. Designed for introductory organic chemistry laboratory courses, the experiment emphasizes the real-world…
