What is another word for electron spin resonance?
Pronunciation: [ɪlˈɛktɹɒn spˈɪn ɹˈɛzənəns] (IPA) 
Electron spin resonance (ESR) is also known as electron paramagnetic resonance (EPR), which involves the interaction of electromagnetic radiation with unpaired electrons in a magnetic field. Other synonyms for ESR include electron magnetic resonance, paramagnetic resonance, and electron spin magnetic resonance. These terms refer to the same phenomenon, which is the measurement of the energy difference between two spin states of unpaired electrons in a sample. ESR or EPR is commonly used in chemistry and physics research to investigate the chemical and physical properties of molecules, such as free radicals, metal complexes, and biomolecules. By studying the ESR spectra, scientists can obtain valuable information about the electronic structure and dynamics of the sample.
