Nuclear magnetic resonance - Wikipedia

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 frequency of the nuclei, which depends on the strength of the static magnetic field, the c… WebC/CS/Phys C191 Spin measurement, spin initialization, spin manipulation I (precession) 10/16/05 Fall 2007 Lecture 15 1 The Hamiltonian with spin Previously we discussed the Hamiltonian in position representation.
