Magnetic chemistry and its possible applications in analytical spectroscopy and related fields. By Matthew Burns – Chemist 9/13/19 abstract Developments in chemistry have stemmed from applying principles from other fields that develops into a field itself. Magnetism applied to chemistry - Magnetic chemistry is one of them. Taking electrochemistry that uses an electric field/current inducing a reaction that doesn’t occur in natural conditions; magnetic chemistry uses a magnetic field inducing conditions and possibly reactions. Three areas are discussed; principles involved, results from using a magnetic field on hydrocarbon fuels, and possible implements in analytical spectroscopy. Starting on how Faraday’s Induction Law is used in altering compound properties. Then, discussing paramagnetism/diamagnetism of atoms/compounds emphasizing diamagnetic compounds, then on intermolecular forces emphasizing on cohesive forces and pseudo structures formed (“clustering”) then discussing quantum principles - emphasizing electron coupling interactions focusing on angular momenta, spin-orbit interaction, and Zeeman Effect. Then, showing results of how applying a magnetic field alters hydrocarbon fuels properties. Explaining how it reduces the “clustering” of molecules, surface tension, viscosity, pollution and increasing volatility and efficiency. Then explaining how an applied field affects the molecules emphasizing on how increasing field strength increases affects and mentioning on how it actually enhances infrared and UV-Vis spectra. Then discussing how the results can be applied to analytical spectroscopy. The increased volatility can improve atomization/nebulization for ICP and GC, thus more target compounds analyzed with less waste reducing need for derivatizing agents. Spectra enhancement for spectra signals that are very weak in infrared and UV-Vis spectroscopy. Reducing mobile phase surface tension/viscosity thus conditions (flow rate, etc.) better adjusted for HPLC. Then showing how a NMR field can be used to do this. Concluding, magnetic chemistry can be utilized to change properties/conditions of compounds and possibly induce reactions. By discussing underlying principles involved; Induction Law, paramagnetism, diamagnetism, intermolecular forces, and quantum principles, explaining how it occurs and results on applying a magnetic field to hydrocarbon fuels which has possible uses in analytical spectroscopy.
