1. Description
The basic equipment set for ESR/NMR experi-
ments is used in conjunction with the ESR sup-
plementary 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. Reso-
nance 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 sup-
plies, while 1000638 is for 230 V (±10 %).
2. Equipment supplied
1 Basic unit
1 Pair of magnetic coils
1 Control console
1 Plug-in power supply, 12 V AC (230 V, 50/60 Hz)
or
1 Plug-in power supply, 12 V AC (115 V, 50/60 Hz)
The basic unit also has a mechanism for ac-
commodating 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 power-
supply voltages for the test probe being used
and for the pair of coils. It also provides a suit-
able signal for an oscilloscope and displays the
value of the high-frequency signal in Hertz.
The pair of magnetic coils allows an adjustable mag-
netic field to be generated at the sample location.
