Interpreting NMR spectra is a skill that every chemist needs, but it requires practice and experience. A recent paper describes a new interactive website that offers many NMR assignment exercises based on experimental one- and two-dimensional spectra. Working through this website allows a user to practice and improve their NMR assignment skills. In addition, there are several other websites available that provide NMR spectra, along with MS and IR data, for users to try their hand at. This post lists some of the currently available resources.
