If a weaker radiofrequency alternating magnetic field, having the frequency of precession of the electron is applied at right angles to fixed magnetic field, which of the following occurs?
(a) Fragmentation
(b) Scattering
(c) Resonance
(d) Absorption
I had been asked this question during a job interview.
This is a very interesting question from Electron Spin Resonance in section Electron Spin Resonance Spectrometers of Analytical Instrumentation
