“…This provides an opportunity to reinforce the importance of symmetry and dipole moment changes to spectroscopy. Lastly, the requirement for symmetric rotational wave functions 14 is in direct contrast to the antisymmetric wave functions of electrons (Fermions) that students commonly discuss in quantum mechanics lectures and that are the basis of the Pauli exclusion principle. This presents a unique student experience of Bose statistics that is rare in undergraduate physical chemistry courses.…”

Rovibrational spectroscopy is a fundamental component of most physical chemistry curricula. This article describes an adaption of the rovibrational spectroscopy of carbon dioxide experiment that can be used as a stand-alone experiment or in conjunction with a traditional hydrogen chloride experiment. The case is made that the laboratory investigation of carbon dioxide provides students with an alternative learning experience to hydrogen chloride experiments alone because the spectroscopic properties of carbon dioxide facilitate a wider discussion and integration of important physical chemistry concepts either directly or peripherally related to rovibrational spectroscopy. However, the motivation to use carbon dioxide is driven by green chemistry considerations. By applying a systems thinking approach to the green chemistry principle of reducing or eliminating toxic reagents, the proposed experiments use only ambient atmospheric carbon dioxide to completely eliminate any purchased reagent. Additionally, without the need for vacuum lines, pumps, traps, and IR gas cells to prepare a sample, instructors can discuss with students the concept of the total chemical footprint of an experiment in relation to not only the reagents but the equipment used to perform the experiment. The use of carbon dioxide also facilitates a discussion of issues related to climate change that reinforces the systems thinking methodology to green chemistry.

“…Very early on, chemistry students are exposed to the necessity of symmetry considerations in chemistry (Glasser, 1967;Jaffe ´, 2013). Typically, this is done with a focus on small molecules (McKay & Boone, 2001;Orchin & Jaffe, 1970;Zeldin, 1966), for example in the context of molecular syntheses (Brown, 1971;Caserio, 1980), or the implications of symmetry on spectroscopic properties (Carlos, 1968;Harris & Bertolucci, 2014;Myrick et al, 2004).…”

The ability to imagine symmetry and the spatial arrangement of atoms and molecules is crucial in chemistry in general. Teaching and understanding crystallography and the composition of the solid state therefore require understanding of symmetry elements and their relationships. To foster the student's spatial imagination, models representing a range of concepts from individual rotation axes to complete space groups have been designed and built. These models are robust and large enough to be presented and operated in a lecture hall, and they enable students to translate conventional 2D notations into 3D objects and vice versa. Tackling them hands-on means understanding them.

“…[96,97] To introduce students to this topic, teaching usually focuses on small molecules, [98][99][100] for example in the contexts of organic synthesis [101,102] or spectroscopy. [103][104][105] However, teaching the introductory courses in general and inorganic chemistry (B.Che.1001 and B.Che.4104) and courses on crystallography (M.Che.1130 and M.Che.1131) at the University of Göttingen over the last few years it has been noticed that precisely these competences of first-year students are increasingly dwindling. Accordingly, more and more time must be spent in undergraduate teaching on introducing them.…”
