研究目的
To provide instructors with different visual frameworks and exercises for the introduction of spectroscopy in the undergraduate classroom and laboratory, aiming for students to understand the experimental spectroscopic techniques at a deeper level.
研究成果
The paper concludes that understanding the basic principles of light–matter interactions is crucial for introducing different forms of spectroscopies. It provides students with an overview of the different processes while considering what occurs on a molecular level, using energy level diagrams to visualize what can be measured in an experiment.
研究不足
The paper does not explicitly mention limitations, but the complexity of the molecules used might make it difficult for students to investigate the nature of selection rules for IR and Raman spectroscopy thoroughly.
1：Experimental Design and Method Selection:
The paper discusses the interactions of electromagnetic radiation with matter, focusing on scattering, absorption, and emission processes. It uses concept maps and visual tools to assist students in understanding these processes.
2：Sample Selection and Data Sources:
The study uses three fluorophores (quinine monohydrochloride dihydrate, fluorescein, and rhodamine B) for comparing different spectroscopic techniques.
3：List of Experimental Equipment and Materials:
Not explicitly mentioned, but implies the use of UV/vis, fluorescence, IR, and Raman spectrometers.
4：Experimental Procedures and Operational Workflow:
Students are guided through exercises to predict and compare spectra for the three fluorophores using different spectroscopic methods.
5：Data Analysis Methods:
The paper emphasizes the importance of understanding the underlying processes of each spectroscopic technique to interpret the spectra correctly.
