Fourier Transform Nuclear Magnetic Resonance (FT-NMR) spectroscopy is based on the principle that certain atomic nuclei possess spin and behave like tiny magnets when placed in a strong external magnetic field. When these nuclei are exposed to a short, intense radiofrequency (RF) pulse, they absorb energy and are excited from a lower energy spin state to a higher energy state. After the RF pulse is turned off, the nuclei return to equilibrium and emit signals called free induction decay (FID). This time-domain signal contains information about all the resonating nuclei in the sample. Using mathematical Fourier
