“…To cover a wide range of potential outputs, three exercises that have been previously published were selected for each of the following courses: general chemistry, organic chemistry, analytical chemistry, physical chemistry, biochemistry, and inorganic chemistry. − The list of all laboratory exercises used for each course and the citations for them are provided in Figure . (We note that these titles may not exactly match titles used in reference publications; this is because using more descriptive titles in our queries generated better ChatGPT outputs.…”

AI technologies are rapidly pervading many areas of our world. AI-driven text generators such as ChatGPT are at the forefront of this due to their simplicity and accessibility. Their influence on higher education is already being observed, and perceptions among faculty and students vary widely. We have undertaken a cross-curriculum study of ChatGPT’s ability to generate laboratory reports. AI-generated reports from general, organic, analytical, physical, inorganic, and biochemistry courses were graded as if they were student reports and analyzed for grade distributions and common strengths and weaknesses. To further gauge ChatGPT’s current impact, we surveyed all students in our Spring 2023 laboratory courses regarding their awareness and use of ChatGPT. We have also laid out suggestions, guidance, and considerations for instructors who wish to prohibit ChatGPT use by their students as well as for those who wish to begin incorporating this new, powerful tool into their teaching.

“…The first example of a rotationally resolved HCl infrared (IR) spectrum in this Journal along with a discussion of the theory was from Stafford et al in 1963 . Since that time, papers have been published about different aspects of the HCl/DCl experiment including the following: increasing the resolution of the spectrum, using computer programs or spreadsheets to analyze the data, − simulating the spectra, modeling potential curves, , and connecting it with statistical mechanics. , The HCl/DCl IR experiment is so prevalent that there are many journal articles devoted to describing safe and efficient techniques to generate HCl and DCl gas in the physical chemistry laboratory. − …”

A version of the classic rotationally resolved infrared (IR) spectrum of a diatomic molecule experiment has been developed using the POGIL framework to more fully engage students in the collection, modeling, analysis, and interpretation of the data. An analysis of the experimental protocol reveals that the POGIL approach actively engages students in scientific practices. The student learning objectives for this laboratory experiment are to (1) develop an energy level diagram and relate that diagram to rotational–vibrational spectra; (2) identify, describe, and interpret the molecular constants that can be extracted from gas-phase IR spectra; (3) discover the impact of spectral resolution on precision of molecular constants derived from the spectral data; and (4) use data to evaluate and refine quantum mechanical models. The learning cycles, analysis of student engagement with scientific practices, and reflections from instructors are described.
