Pulse Fourier Transform NMR
A short, powerful RF pulse excites all nuclei of one isotope simultaneously; the decaying time-domain signal (FID) is digitized and Fourier transformed into a frequency-domain spectrum. Relaxation back to equilibrium sets how fast pulses can be repeated for signal averaging.
This Concept is waiting for its first lesson!
