Radiofrequency Pulses: Response of Nuclear Spins

Pulse FT NMR of non-equilibrium states of half-integer spin quadrupolar nuclei in single crystals

“…In pulse Fourier transform, FT, NMR, radio-frequency pulses are applied to a nuclear spin system to yield a free induction decay response in the time domain which is then Fourier transformed to produce the spectrum in the frequency domain [1][2][3][4]. The FT NMR experiment generally begins with the nuclear spin system at thermal equilibrium, thus the resulting NMR spectrum is representative of the true initial population differences of the energy levels involved in the transition(s).…”
