NMRium: Teaching nuclear magnetic resonance spectra interpretation in an online platform

Abstract

NMRium is the first web-based software that allows displaying, processing, interpretation, and teaching of 1D and 2D NMR data in a user-friendly interface. It can import the most common data formats (e.g., JCAMP-DX, Bruker, Varian, and Jeol). While the scope for the use of NMRium encompasses a variety of applications such as being a component in data repositories or electronic lab notebooks (ELN), performing structure elucidation or preparing raw spectral data for publication, it also excels in enhancing teaching of NMR interpretation. In this paper, we present some current possibilities of this new tool. Several series of exercises are already provided on https://www.nmrium.org/teaching.

“…Students were responsible for interpreting the results obtained from these characterization techniques. 46 Regarding the crude 1 H NMR analysis (Figure 2), the signals within the range 5.4−6.2 ppm correspond to the protons on the double bond of the monomer (Ha). Notably, these signals were absent from the 1 H NMR spectrum of the purified polymer (see Figures S4, S6, S9, and S11), confirming the successful removal of the unreacted monomer from the final product.…”

“…After the purification step, 1 H NMR analysis was performed to verify that the polymers were properly purified and all of the unreacted monomers were removed. Students were responsible for interpreting the results obtained from these characterization techniques . Regarding the crude 1 H NMR analysis (Figure ), the signals within the range 5.4–6.2 ppm correspond to the protons on the double bond of the monomer (Ha).…”
