Electron Spin Resonance Spectrometer (ESR) History of ESR. ESR See also → nuclear magnetic resonance Vedyagin Aleksey A., Bedilo Alexander F., Mishakov Ilya V., Shuvarakova Ekaterina ‘Spectroscopic methods as NMR and electron spin resonance considered thereafter are sensitive to short-range interactions and appropriate to the measurement of the molecular order and dynamics.’ An advanced pulse ESR approach, in particular the electron spin echo (ESE) technique, allows efficient time selection for spins having different relaxation times. In 1945, the physicist Zavoisky of the former Soviet Union published a report in a Soviet physics journal on the first successful observation of ESR absorption. English loves putting words together to make new ones. Changes in the spin of unpaired electrons cause radiation to be absorbed at certain frequencies. Introduction Electron spin resonance (ESR) spectroscopy has been used for over 50 years to study a variety of paramagnetic species. Electron paramagnetic resonance (EPR), also called electron-spin resonance (ESR), selective absorption of weak radio-frequency electromagnetic radiation (in the microwave region) by unpaired electrons in the atomic structure of certain materials that simultaneously are subjected to a constant, strong magnetic field.The unpaired electrons, because of their spin, behave like tiny magnets. Electron spin resonance dating, or ESR dating, is a technique used to date newly formed materials which radiocarbon dating cannot, like carbonates, tooth enamel, or materials that have been previously heated like igneous rock.Electron spin resonance dating was first introduced to the science community in 1975, when Motoji Ikeya dated a speleothem in Akiyoshi Cave, Japan.
