Published Works

Donald McQuarrie has numerous publications in the science literature, ranging from basic chemistry to quantum and molecular chemistry. Each of these books were popular for having long publication runs. McQuarrie’s texts were often classified as overly comprehensive. In addition, he also has authored or co-authored 95 scientific papers.

One of McQuarrie’s most cited publications include nuclear magnetic resonance, or NMR, spectroscopy¹. He emphasized the idea that a proton acts as a tiny magnet, and when an external magnetic field is applied, the protons will align. This will cause electromagnetic energy to be absorbed or emitted. For different, unequivalent molecules, different magnetic field interactions take place. Protons must belong to chemically equivalent hydrogen atoms in order to absorb the same magnetic field magnitude along the spectra. The equation to define dissimilar proton molecules is

$H_{effective}=H_{0}-H_{shielding}$

where H_effective is the magnetic field actually applied to a proton, H₀ is the electric field being applied, and H_shielding is the magnitude of shielding due to its electron density. McQuarrie explains its usefulness in allowing to identity different structural bonds in chemical structures. This idea has many subsets of rules which will define more specific bond structures, such as multiplets. Graphically, different proton interactions produce signals by creating a chemical shift which are unique in shape and size to their magnetic strength. The signals presented on a PMR graph are defined by the area under the signal, not the relative height. This all helps in identify that amount, location, and structures which the proton is characterized by.
