Question

For high resolution work the magnetic field over the entire sample volume must be maintained uniform in space and time.

(a) True

(b) False

I had been asked this question during an interview.

The doubt is from Continuous Wave NMR Spectroscopy in section Nuclear Magnetic Resonance Spectrometer of Analytical Instrumentation

Answer 1

Right answer is (a) True

To explain I would say: For high resolution work the magnetic field over the entire sample volume must be maintained uniform in space and time. To do this all the components must be kept in specified conditions.
