Electron-spin-resonance/electron-paramagnetic-resonance spectroscopy of iron-sulphur enzymes

Biochemical Society Transactions, 1985
The conjugated iron-sulphur proteins are enzymes that contain iron-sulphur clusters, which are paramagnetic in certain oxidation states. Numerous enzymes of this type have been isolated (Palmer, 1975; Cammack, 1979; Yoch & Carithers, 1979), and whole books have been devoted to them (Lovenberg, 1977; Spiro, 1982).

Dipolar spectroscopy and spin alignment in electron paramagnetic resonance

Chemical Physics Letters, 2000
Abstract Two single-frequency techniques for refocusing (SIFTER) dipolar couplings between electron spins are introduced. The experiments are based on the solid-echo and Jeener–Broekaert sequences, well established in dipolar NMR spectroscopy of solids, and open up new routes to high-resolution two-dimensional EPR spectroscopy with only moderate ...

Electron Spin Resonance Spectroscopy (Esr)

1986
Electron spin resonance (esr) (also known as electron paramagnetic resonance, epr) has been successfully applied to biological problems since the late 1950s (Commoner et al., 1957). The method compares closely with nmr in being essentially nondestructive since the measuring wavelengths fall within the microwave portion of the spectrum, corresponding to

Radiostability of Allantoin by Using Electron Spin Resonance Spectroscopy

Spectroscopy Letters, 2013
ABSTRACT The radiosterilization potential and dosimetric feature of allantoin were investigated through the molecular degradations produced after ultraviolet and gamma irradiation using electron spin resonance, infrared, and ultraviolet spectroscopies and thermal measurement techniques (differential thermal analysis and the glass transition temperature)

Single-chip detector for electron spin resonance spectroscopy

Review of Scientific Instruments, 2008
We have realized an innovative integrated detector for electron spin resonance spectroscopy. The microsystem, consisting of an LC oscillator, a mixer, and a frequency division module, is integrated onto a single silicon chip using a conventional complementary metal-oxide-semiconductor technology.

Eumelanins and Pheomelanins: Characterization by Electron Spin Resonance Spectroscopy

Science, 1982
Synthetic dopa melanin and cysteinyldopa melanin have different electron spin resonance spectra. Data are reported for mixtures of these melanins and for dopa-cysteinyldopa copolymers, which are spectroscopically similar. A simple parameterization of the spectra allows estimation of the relative amounts of (i) dopa melanin and cysteinyldopa melanin in ...

Electron Spin Resonance (ESR) Spectroscopy

2005
Electron spin resonance (ESR) spectroscopy, invented by Zavoiskii in 1944, is similar to NMR spectroscopy. ESR spectroscopy is an absorption spectroscopy which involves the absorption of radiation in the microwave region (104–106 MHz) by substances containing one or more unpaired electrons.
