Nuclear chemistry is a subfield of chemistry dealing with radioactivity, nuclear processes and nuclear properties. It may be divided into the following categories:
Radiochemistry deals with the use of radioactivity to study ordinary chemical reactions
The application of techniques from chemistry to study nuclear reactions such as fission and fusion — see also nuclear physics.
Isotopic chemistry deals with the effect of nuclear mass on chemical reactions and the properties of compounds
NMR/Spectroscopic Chemistry , or nuclear magnetic resonance, uses the spinning of an atom when energy is absorbed by it to identify the atom.
