Nuclear Quadrupole and Zero-field Nuclear Magnetic Resonance Spectrometer
Equipment
Seen in the image is a nuclear quadrupole and zero-field nuclear magnetic resonance spectrometer that was photographed at the department of physics. The spectrometer covers a range of 120cMHz-350 MHz and can be used to study the properties of solids by NQR spectroscopy, viz. chemical inequivalence, nature of the electric field gradient, bond characters etc. Molecules containing bromine and some iodine nuclei can be studied using this instrument. Zero-field NMR studies in ferromagnetic alloys can also be undertaken using this spectrometer, viz. determination of internal magnetic fields, variation of saturation magnetization with temperature, temperature variation of quadrupole coupling constants, study of the rotation of the direction of the easy axis of magnetisation with temperature etc. The accessories seen in the image are the liquid nitrogen dewar and the Zeeman magnet assembly.
