Spin Magnetic Moments

Basis for spin magnetic moments
A spin magnetic moment is induced by all charged particles. The electron is an example of one such charged particle. A spin magnetic moment is created because a particle has physical properties known as spin and electric charge. The spin within classical physics would be an object that rotates axially around its center of mass. In quantum mechanics,elementary particles are points, which have no axis to revolve around. This means these particles do not have spin in a classical sense, as angular momentum is defined by , but have the physical property of angular momentum (see Spin (physics)). Maxwell's theory of magnetic fields dictates that any moving charged particle creates amagnetic moment, and by definition, angular momentum designates movement. This is where the magnetic moment emerges in classical electromagnetism.
Spin in chemistry
Spin magnetic moments create a basis for one of the most important principles in chemistry, the Pauli exclusion principle. This principle, first suggested by Wolfgang Pauli, governs most of modern-day chemistry. The theory plays further roles than just the explanations of doublets within electromagnetic spectrum. This additional quantum number, spin, became the basis for the modern standard model used today, which includes the use of Hund's rules, and an explanation of beta decay.
