Electron spin resonance (ESR) or electron paramagnetic resonance (EPR) spectroscopy is an experimental technique for detecting and characterizing chemical systems bearing one or more unpaired electrons.... emphasis will be given to the different types of spectra observed according to the physical state of the investigated sample (liquid. Electron ionization was first described in 1918 by Canadian-American Physicist Arthur J. Dempster in the article of "A new method of positive ray analysis." It was the first modern mass spectrometer and used positive rays to determine the ratio of the mass to charge of various constituents.

Suggest the decreased spin signal is due to a 0.20 nm thick "dead layer" at the sample surface in which EPR active radicals are absent (Figure 1). Due to force-sensitivity limitations, this dead layer poses a significant challenge to MRFM detection of single electron spins.

Out of the two possible relaxation processes, the spin-spin relaxation is very efficient, unless the sample is extremely dilute. The spin-spin relaxation time comes out to be 10–6to 10–8 s, much shorter than the spin-spin relaxation time in case of NMR. Where h is Planck's constant, 6.626 × 10 −34 J second; ν is the frequency of the electromagnetic radiation, g is the so called g-factor (or Lande splitting factor), B 0 is the magnetic field of the laboratory magnet in Tesla (T), and β is the Bohr magneton of electron, 9.2740 × 10 −24 J/T. EPR spectra are usually recorded at constant microwave frequency and changing magnetic field and. ESR-6 Ε = electron Zeeman energy + nuclear Zeeman energy + electron-nuclear coupling = geµeMSB + i ∑ gNiµNiMIi (1-σi)B + i ∑ ai MSMIi (8) MS is the quantum number that measures the component of the spin angular moment along the field direction (z). The ai stand for the hyperfine coupling constant which denotes the interaction between the nucleus and the electron.

The electron spin aligned parallel to the applied magnetic field B0, and a high-energy state in which the electron spin is aligned against the applied magnetic field. The energy difference between these states, ΔE, is given by ΔE = g β B0 (1) where g is termed the "g-factor" and is approximately 2. β is a physical constant known as the. EPR [] is a magnetic resonance technique which detects the resonance transitions between energy states of unpaired electrons in an applied magnetic field.The electron has spin, which gives it a magnetic moment. The magnetic moment makes the electron behave like a tiny bar magnet. When we apply an external magnetic field, the paramagnetic electrons can either orient in a direction parallel or.
