Abstract

Many researchers and teachers in chemistry education have focused on the benefits of analyzing and interpreting UV, IR and NMR spectra. This has the result of allowing students to more easily analyze a spectrum in terms of molecular parameters and ultimately molecular structures, while having difficulty understanding basic concepts and features of spectroscopy, such as the resolution or resolving ability. In order to make this concept more understandable by students, an instructional analysis is proposed. The analogy is between the most advanced internationally optical telescope (the Gran Telescopio Canarias) and the NMR spectrometer with the highest resolution (the AVANCE 1000). We also report the results of an intervention study, with fourth-year undergraduate chemistry students.
