Zeeman first observed the strange behavior of certain nuclei when subjected to a strong magnetic field at the end of the nineteenth century, but the practical use of the so-called “Zeeman effect”was only made in the 1950s when NMR spectrometers became commercially available. Notes: This is a great little matching problem that gets to the heart of pattern recognition, coupling, and symmetry in 1 H NMR spectroscopy. This archive includes six types of problems from the midterm and final exams of my Chem 203 Organic Spectroscopy class. However, it is use-ful, especially for understanding more complex experiments, to think about how the familiar NMR spectra we see are related to energy levels. In other words, frequencies for chemicals are measured for a 1 H or 13 C nucleus of a sample from the 1 H or 13 C resonance of TMS.
