Thomas D. Varberg – Journal of Chemical Education, 2022
An experiment for the undergraduate physical chemistry laboratory is described in which the Raman spectrum of liquid "para"-difluorobenzene is recorded and assigned. A density functional theory (DFT) calculation of the 30 normal modes of the molecule is undertaken using computational chemistry software. Students use group theory to…

Hadi D. Arman; Tu M. Ho; Kaitlyn Varela; Cynthia S. Veliz; Richard B. Zanni; Armando Rodriguez; Zhiwei Wang; Francis K. Yoshimoto – Journal of Chemical Education, 2023
Eleven different laboratory experiments were designed and executed throughout a semester to provide a meaningful research experience for 23 undergraduate biochemistry majors at UTSA. The topic of the semester was based on the idea of exploring new aspects to enhance our understanding of how the human body uses cytochrome P450 enzymes to metabolize…

Kaltcheva, Nadia; Nenkova, Maia – Physics Education, 2021
Many introductory astronomy courses include concepts related to basic stellar properties. In general, these are concepts that originate from the human perception of starlight. This observational aspect is not easy to incorporate in the classroom. We explore if these concepts could be developed using the built-in data in a planetarium software.…

Stelz-Sullivan, Eleanor J.; Marchetti, Barbara; Karsili, Tolga – Education Sciences, 2022
Computational and atmospheric chemistry are two important branches of contemporary chemistry. With the present topical nature of climate change and global warming, it is more crucial than ever that students are aware of and exposed to atmospheric chemistry, with an emphasis on how modeling may aid in understanding how atmospherically relevant…

Ugone, Valeria; Garribba, Eugenio; Micera, Giovanni; Sanna, Daniele – Journal of Chemical Education, 2015
In this laboratory activity, the equilibrium between square pyramidal and octahedral V(IV)O[superscript 2+] complexes is described. We propose a set of experiments to synthesize and characterize two types of V(IV)O[superscript 2+] complexes. The experiment allows great flexibility and may be effectively used at a variety of levels and the activity…

Marty, Michael T.; Beussman, Douglas J. – Journal of Chemical Education, 2013
An in-depth understanding of all parameters that affect an instrumental analysis method, allowing students to explore how these instruments work so that they are not just a "black box," is key to being able to optimize the technique and obtain the best possible results. It is, however, impractical to provide such in depth coverage of…

Frey, E. Ramsey; Sygula, Andrzej; Hammer, Nathan I. – Journal of Chemical Education, 2014
This laboratory exercise introduces undergraduate chemistry majors to the spectroscopic and theoretical study of the polycyclic aromatic hydrocarbon (PAH), corannulene. Students explore the spectroscopic properties of corannulene using UV-vis and Raman vibrational spectroscopies. They compare their experimental results to simulated vibrational…
