(Phys.org) —Today's nuclear magnetic resonance (NMR) and Magnetic Resonance Imaging (MRI) technologies, like quantum information processing and nuclear spintronic technologies, are based on an intrinsic . More subtly, a low field and correspondingly low .. Mixtures through effective inversion of long-range dipolar interactions. Pulsed EPR provide new experiment possibilities, like in pulsed NMR, correlation experiment are possible, allowing measurement of long range dipolar coupling. GO Experimental pulse NMR Author: Eiichi Fukushima, Stephen B.W. This power was determined by measuring the peak-to-peak voltage of the pulse seen by the probe circuit by routing this pulse to a 50 Ω-terminated oscilloscope. To produce the 100 μs π/2 pulse in our experiments. This experimental system of pulsed NMR consists of pulse series generator, RF pulse generator, RF switching amplifier, detection probe, and magnet. Below is an approximate image of a realistic square 5μs long pulse. Radiofrequency pulse or "RF pulse" is a temporary burst of radio waves which serves as a basic element of any pulsed NMR experiment. For the experiment, researchers at Los Alamos's TRIDENT facility focused an extremely short and intense laser pulse onto an ultra-thin foil of deuterated plastic—a material in which hydrogen atoms within the foil were replaced with deuterium isotopes. In NMR experiments and quantum computation, many pulse (quantum gate) sequences called the composite pulses, were developed to suppress one of two dominant errors; a pulse length error and an off-resonance error. At low frequencies, the electrical skin depth is no longer small compared to wire diameters, a regime in which optimal NMR SNR performance has not been explored experimentally, to our knowledge.
