Jiachen Li; Guanzhou Zhu; Peng Liang; Hongjie Dai – Journal of Chemical Education, 2024
An integrated laboratory experience in X-ray photoelectron spectroscopy (XPS) is designed for undergraduate and graduate students in chemistry, materials science, and other related fields. Focusing on ubiquitous Si, Cu, and their common oxides, students are guided to characterize a series of standard materials by XPS to understand the fundamentals…

Armélinda Agnello; Jean-François Focant – Journal of Chemical Education, 2025
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,…

Frédéric Hapiot; Pierre-Edouard Danjou; François Delattre; Solen Josse; Véronique Bonnet – Journal of Chemical Education, 2025
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…

T. Leon Venable – Journal of Chemical Education, 2024
As an introduction to quadrupolar effects in NMR spectroscopy, students use low field ([superscript 1]H, 60 MHz), benchtop [superscript 13]C NMR spectroscopy to contrast the spin-spin coupling behavior of [superscript 13]C to the dipolar [superscript 1]H and quadrupolar [superscript 2]D in familiar solvents C(H/D)Cl[subscript 3], C(H/D)[subscript…

Mariur Rodriguez Moreno; Nye C. Johnson; Christopher B. Stewart; Mary L. Setelin; Adam X. Wayment; Braxton M. Felix; Scott R. Burt; David J. Michaelis – Journal of Chemical Education, 2024
We describe a three-day advanced organic laboratory experience that includes the solid-phase synthesis of an unknown three amino acid polypeptide for junior/senior undergraduate chemistry majors. Students conduct a series of 1D and 2D NMR experiments (HSQC, HMBC, TOCSY) and analyze the data to identify the side chain residues of the peptide and…

Ye Jiang; Xin Sun; Guomeng Zhang; Da Han; Zhengda Yang – Journal of Chemical Education, 2024
The flue gas from waste incineration power plants contains high-level zinc species that may deactivate the catalyst for selective catalytic reduction (SCR) of nitrogen oxides (NO[subscript x]) with NH[subscript 3]. A comparison experiment was designed to investigate the effect of different types and Zn/Ce molar ratios on the performance of…

Robert D. Milligan; Donald J. Wink – Journal of Chemical Education, 2024
A key part of the practice of chemistry is the analysis of chemical composition, including through gravimetric analysis and spectrophotometry. However, the complexity of doing multiple calculations to obtain analytical evidence, such as that required to determine an empirical formula, presents a challenge if such analytical methods are to be…
