Answer #1

1. In FT NMR the resonance are not measured one after another, but all nuclei are excited at the same time by a radio frequency pulse.

2. The excited nuclei will spin, which will emit the radiation after the pulse

3. The emitted signal is a superposition of all excited frequencies its evolution in time is recorded, the intensities of several frequencies which gives the observed signal in their superposition are calculated by a mathematical operation called Fourier Transformation..
