dna nmr spectrum analysis tutorial

Nuclear magnetic resonance nmr is a physical phenomenon in which nuclei in a strong constant magnetic field are perturbed by a weak oscillating magnetic field in the near field and respond by producing an electromagnetic signal with a frequency characteristic of the magnetic field at the nucleus this process occurs near resonance when the oscillation frequency matches the intrinsic.
