More on the way

Experimental topics that can be studied with the unit include:

• Resonance absorption of a high-frequency oscillating circuit
• Dependence of resonance frequency on magnetic fields
• Resonant line widths
• Electron and proton spin
• Magnetic moment of atomic particles and nuclei
• Determination of nuclear g-factors
• Nuclear-spin tomography
 
 
The ESR/ NMR control unit is used in conjunction with the ESR module (1022705) to investigate electron spin resonance (ESR) in DPPH (diphenyl picryl hydrazyl) and with the NMR module (1022706) to study nuclear magnetic resonance (NMR) in glycerine, polystyrene and Teflon. 
Resonances can be observed as a result of transitions induced by high frequencies due to changes in an external magnetic field. Reso-nance absorption curves can be viewed using a simple dual-channel oscilloscope. 
The control console provides control and pow-er-supply voltages for the test probe being used and for the pair of coils. It also provides a suitable signal for an oscilloscope and displays the value of the high-frequency signal in Hertz. 
The ESR/NMR control unit numbered 1022700 is designed for 230 V/ 50-60 Hz (±10 %) mains voltage supplies, while 1022702 is for 115 V/ 50-60 Hz (±10 %).
