ESR, Electron Spin Resonance measures number of charges occupying deep traps in crystal band gap.
Electron Paramagnetic Resonance (EPR) or Electron Spin Resonance (ESR) is a spectroscopic technique which detects species that have unpaired electrons, generally meaning that the molecule in question is a free radical if it is an organic molecule, or that it has transition metal ions if it is an inorganic complex. Because most stable molecules have a closed-shell configuration without a suitable unpaired spin, the technique is less widely used than nuclear magnetic resonance (NMR). The EPR was first discovered in Kazan State University by Soviet physicist Yevgeniy Zavoyskiy in 1944

Electron Spin Resonance (ESR) and Fossil DNA:
Electron Spin Resonance (ESR) dating is a method used to date fossil teeth and shells by measuring the accumulated radiation dose. This technique is particularly useful for dating fossil remains that are too old for radiocarbon dating. By measuring the amount of trapped electrons in the mineral structure of teeth or shells, scientists can estimate the age of the fossils.
Fossil DNA analysis is another method that has revolutionized the field of paleontology. By extracting and analyzing DNA from fossils, scientists can determine the relationships between different species and reconstruct evolutionary histories. This method has provided valuable insights into the genetic diversity and evolutionary relationships of extinct organisms.
By combining ESR dating with fossil DNA analysis, scientists can now obtain more precise and accurate age estimates for fossil remains. This has led to the revision of evolutionary periods for different groups of organisms and has improved our understanding of the history of life on Earth.
