Nuclear Magnetic Resonance NMR Instrument

This Nuclear Magnetic Resonance (NMR) experiment system is designed to demonstrate the fundamental principles and phenomena of nuclear magnetic resonance. It enables students to observe the NMR signals of hydrogen (¹H) and fluorine (¹⁹F) nuclei, measure the nuclear g-factor and nuclear magnetic moment, and gain practical experience in magnetic resonance techniques. Note: A dual-trace oscilloscope is required but not included. Physics Lab Experiments from Atico Exports.
