Question 17
Electron spin resonance (ESR) is an analytical technique that
is based on the spin of an electron. What types of substances are analyzed
using ESR spectroscopy? State some examples of the uses of ESR in at
least two different areas.
Electron
Spin Resonance
This page describes ESR, a dating technique that can be used repeatedly
on the same sample, and which can be used to date things such as tooth
enamel.
Electron
Paramagnetic Resonance
This page describes the use of EPR spectrometers to discriminate between
very similar chemical samples. The technique can even obtain spectra
from living animals and perfused organs.
Applications
of EMR
This page provides a list of all of the fields, from Archaeology to
Biology, that make use of EMR spectroscopists.

for medical diagnosis. How is this technique similar to and different
from electron spin techniques? Provide some examples of the usefulness
of MRI results. What political issue is associated with MRI use?
The
Basics of MRI
The author of this source is a professor at the Rochester Institute
of Technology. The website is a large collection of pages about MRI,
organized into 13 chapters. It goes into quite a bit of detail, yet
it reads quite easily.
