Eduscope India is a leading Nuclear Magnetic Resonance Apparatus
Quick Answer:Nuclear Magnetic Resonance Apparatus introduces students to NMR, the phenomenon in which nuclei such as hydrogen protons absorb energy at a resonance frequency inside a magnetic field.
The apparatus uses the CW (continuous wave) technique, continuously irradiating the sample at a fixed frequency while the magnetic field is swept slowly through resonance. Using this method, students can observe hydrogen proton resonance in six different chemical environments, directly showing how a hydrogen nucleus's local chemical surroundings shift its resonance condition, and a supplied fluoride sample allows fluorine resonance to be observed and compared against the hydrogen results. Beyond this basic observation, the nuclear magnetic moments of the hydrogen proton and fluorine nucleus can be measured, and — if a gaussmeter is available — the gyromagnetic ratios of both nuclei can be independently determined, the ratio that fixes a nucleus's resonance frequency in a given field. This is the same nuclear physics lab equipment India phenomenon used in MRI medical imaging and NMR spectroscopy, first observed by Isidor Rabi and developed further by Felix Bloch and Edward Purcell, who shared a Nobel Prize for the work in 1952.
