the appropriate amount of group theory thrown in, would show that magnetic
spectroscopic techniques can determine a lot about atomic and molecular sys-
tems. Because of how the electrons and nuclei interact with each other, we can
derive specific structural information about molecules. Such information,
when combined with information from other sources like vibrational or rota-
tional or electronic spectroscopy, helps give us a perfect picture of what atoms
and molecules look like. All this is based on the theory of quantum mechan-
ics, the explanation for how subatomic particles behave. All of spectroscopy is
a testament to the fact that quantum mechanics works and can give us infor-
mation about the world around us.
