Phases p n are elements of the Frank sequence with length N.. The formal definition of frequency is the time derivative of phase. For the polyphase experiment, frequency at any time in the experiment is formally either 0 or infinity because of the discontinuities in the phase. Electron paramagnetic resonance. Electron paramagnetic resonance ( EPR) or electron spin resonance ( ESR) spectroscopy is a method for studying materials that have unpaired electrons. The basic concepts of EPR are analogous to those of nuclear magnetic resonance (NMR), but the spins excited are those of the electrons instead of the atomic nuclei.

Electron paramagnetic resonance. Electron paramagnetic resonance ( EPR) or electron spin resonance ( ESR) spectroscopy is a method for studying materials that have unpaired electrons. The basic concepts of EPR are analogous to those of nuclear magnetic resonance (NMR), but the spins excited are those of the electrons instead of the atomic nuclei. Rapid scan (RS) is a novel and, at the same time, an ‘aged’ EPR method. The spin system evolution under the rapid-passage conditions was well-understood at the dawn of magnetic resonance.Rapid scan (RS) EPR is the method of choice for spectral-spatial imaging, especially when multi-line spin probes are used. This technique demonstrates higher sensitivity in comparison with the conventional first-derivative continuous-wave (CW) EPR [ 1 – 2, 9 , 24 – 34 ]. RS spectra can be captured on a microsecond time scale.RapidEPR uses the collected data for various purposes: To provide and maintain our services; To notify you about changes to our services; To allow you to participate in interactive features of our services when you choose to do so; To provide customer support; To gather analysis or valuable information so that we can improve our servicesWe collaborate with our fire service and EMS customers to develop and continuously improve our products.
