The Principle & Application of Nuclear Magnetic Resonance (NMR)
Nuclear magnetic moments (along with electronic magnetic moments) precess (spin) when placed in an external magnetic field, B. The frequency at which they precess, called the Lamor precessional frequency, wL, is directly proportional to the magnetic field. When the magnetic moment μ is lined up with the field as closely as quantum physics permits, the…

Basic Properties of Nuclei
All nuclei are made up of two types of particles, namely: protons and neutrons. The only exception is the ordinary hydrogen nucleus, which is a single proton. Atomic Number, Neutron Number, Mass Number and Isotopes The following quantities are used to describe the atomic nucleus: The symbol used to show how many protons and neutrons…
