The International EPR (ESR) Society
has been an internationally active group since its inception in 1989. The Society aims to stimulate scientific development of electron paramagnetic resonance (EPR), also known as electron spin resonance (ESR) spectroscopy, facilitate communication among EPR (ESR) researchers, and encourage the use of EPR (ESR) techniques across a wide variety of research fields. The Society maintains a large database of members who are active in EPR (ESR) research. These members have access to a quarterly newsletter, too. At their annual meetings the Society also presents awards for research in various areas.
