Product Description
ESAW Electron Spin Resonance Spectrometer (EEC-11322)
In this method, use is made of the Zeeman interaction of the magnetic dipoles associated with the nucleus or the electron, when placed in an external magnetic field. Accordingly, they are identified as NMR (Nuclear Magnetic Resonance) or ESR (Electron Spin Resonance). This form of spectroscopy finds many applications in many diverse branches of Physics, Chemistry and Biology.
This set-up is designed, keeping in mind the basic objectives of a classroom experiment. The observation of ESR in low magnetic field and in a radio frequency makes this apparatus very simple, inexpensive and with in reach of every Post Graduate laboratory.
The Electron Spin Resonance experiment comes complete along with following accessories:
(1) Helmholtz coils with an attachment for the ESR-HC
(li) ESRSample : DPPH
(lil) R.F.Oscillator (10MHzto19MHz)
The experiment consists fo the following :-
Argon filled tetrode
Filament Power Supply
3.6-4.3 continuously variable
Power Supply for VG K1
1.3-5Vcontinuously variable
Power Supply for VG A2
1.3-15Vcontinuously variable
Power Supply for VG K2
0-95V Continuously variable
Saw tooth waveform for CRO display
Scanning Voltage :0-80 V
Scanning Frequency : 115+20Hz
Multirange Digital Ammeter
Display : 3%4 digit, LED
7 -8 -9A Range : 10, 10 &10
The instrument can not only lead to a plot of the amplitude spectrum curve by means of point by point measurement, but also directly display the amplitude spectrum curve on the oscilloscope screen. This instrument can thus be used as class room experiment as well as for demonstration to a group of students.
