Abstract: This study introduces a physical chemistry experiment designed for measuring the magnetic susceptibility of metal coordination complexes using nuclear magnetic resonance (NMR) spectroscopy. By observing the shifts in the proton resonance signals of reference substances in solutions containing magnetic metal complexes, we determine the magnetic susceptibility of these complexes. The experiment provides a comprehensive derivation of the underlying principles, optimized procedural steps, and thorough data and error analysis. This method effectively integrates physical chemistry concepts with advanced instrumental analysis techniques, and is tailored to meet the needs of educational settings, making it an excellent addition to undergraduate laboratory courses.

Key words: NMR, Magnetic susceptibility, Evans method, Metal coordination complexes
