NUCLEAR MAGNETIC RESONANCE (NMR)
So lets start from a very basic. Each atom consists of a nucleus and that is very specific to each atom (no two atoms can have same nuclear arrangement). This nucleus is always in spinning motion like a top. This motion of nucleus generate magnetic field because nucleus(contains proton) possesses electric charge and each moving charged species generate the magnetic field . Difference between spinning and precessional motion:- Spinning Precession Simple nucleus is always spinning on its axis. But when this nucleus comes under the external magne...
