Question

Differentapplications of electron spin resonance spectrometer

Answer 1

Electron paramagnetic resonance(EPR) or electron spin resonance(ESR) spectroscopy is a method for studying materials with unpairedelectrons. The basic concepts of EPR are analogous to those of nuclearmagnetic resonance (NMR), but it iselectron spins that are excited instead of the spins of atomic nuclei.

Answer 2

Electron spin resonance (ESR) spectroscopy is able to directly measure the chemical species with unpaired electrons and has been widely used in a number of research fields. This review focused on its application in nutraceutical and food research. Current status of ESR in free radical scavenging capacity estimation, food oxidative stability evaluation, Cu(2+) chelating capacity determination were summarized.
