Nuclear Magnetic Resonance Chemical Instrumentation Center

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 chemica… WebIn the last molecule, proton a is cis to the methoxy group while proton b is cis to the bromine which puts them in different environment and therefore, two NMR signals will be observed.
