1. Description
The basic equipment set for ESR/NMR experiments is used in conjunction with the ESR supplementary set (1000640) to investigate electron spin resonance (ESR) in DPPH (diphenyl picryl hydrazyl) and with the NMR supplementary set (1000642) 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. Resonance absorption curves can be viewed using a simple dual-channel oscilloscope or with the 3B NETlog™ unit.
The ESR/NMR basic set numbered 1000637 is designed for 115 V (±10 %) mains voltage supplies, while 1000638 is for 230 V (±10 %).

The basic unit also has a mechanism for accommodating samples, as well as one for an ESR or NMR test probe (from 1000640 or 1000642) and others for a pair of magnetic coils and a permanent magnet (from 1000642).
The control console provides control and powersupply 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 pair of magnetic coils allows an adjustable magnetic field to be generated at the sample location.
