The main interest of
electron spin resonance lies in the study of free radicals having unpaired electrons.

electron spin resonance, phosphorescence, and thermal studies.
The current research used three dating methods--uranium series,
electron spin resonance and optically stimulated luminescence--to establish that the burial of this man took place between 56,000 and 68,000 years ago.
Electron spin resonance (ESR) analysis has recently become an alternative C14 and thermo-luminescence dating method which can be applied to a variety of problems in geology, archaeology and paleoanthropology (Renfrew C et al., 1992; Jonas 1997; Walker 2005; Grun 1989).
The introduction begins: "In earlier days, electron paramagnetic resonance (EPR) was referred to as paramagnetic resonance (PMR), but today is also referred to as
electron spin resonance (ESR) and, more recently--in analogy with nuclear magnetic resonance (NMR)--as electron magnetic resonance (EMR)." Editor Misra (physics, Concordia U., Canada has brought together contributed chapters offering full treatment of theoretical and practical aspects, and prospects for the future.
Electron spin resonance (ESR) spectroscopy is a valuable tool in the identification of free radicals and the study of the degradation processes in polymers (Ranby and Rabek, 1977).
Now, according to a report in Nature News, a team led by Rainer Grun, a geochronologist at the Australian National University in Canberra, has used
electron spin resonance (ESR) and uranium-series techniques to date the megafauna teeth directly.
