Magnetic resonance spectroscopy (MRS) is used to determine the quantity of metabolites, such as creatine phosphate (PCr) and adenocine triphosphate (ATP), in the living body by collecting their nuclear magnetic resonance (NMR) spectra. In the field of MRS, the frequency spectrum of metabolites is usually obtained by applying the fast Fourier transform (FFT) (Cooley & Tukey, 1965) to the NMR sig...

In this paper, an automatic determination algorithm for nuclear magnetic resonance (NMR) spectra of the metabolites in the living body by magnetic resonance spectroscopy (MRS) without human intervention or complicated calculations is presented. In such method, the problem of NMR spectrum determination is transformed into the determination of the parameters of a mathematical model of the NMR sig...

Abstract In this paper, the epoxy value of resin TDE-85 was measured by proton nuclear magnetic resonance ( 1 H-NMR) spectroscopy and tetraethylammonium bromide titration. Comparisons measurement results repeatability two methods show that NMR can be used to measure TDE-85. However, because high requirements for sample purity, when testing containing impurities, is worse than

We consider two new quantum gate mechanisms based on nuclear spins in hyperpolarized solid Xe and HCl mixtures and inorganic semiconductors. We propose two schemes for implementing a controlled NOT ( CNOT ) gate based on nuclear magnetic resonance ( NMR ) spectroscopy and magnetic resonance imaging ( MRI ) from hyperpolarized solid Xe and HCl mixtures and optically pumped NMR in semiconductors....

A model of (4, 4) single-walled boron-nitride nanotube as a representative of armchair boron-nitride nanotubes studied. At first the structure optimization performed and then Nuclear Magnetic Resonance parameters (NMR) by Density Functional Theory (DFT) method at B and N nuclei calculated. Resulted parameters evaluation presents electrostatic environment heterogeneity along the nanotube and esp...

1. Outline of Basic NMR Principles Nuclear magnetic resonance (NMR), as all spectroscopic methods, relies upon the interaction of the sample being examined with electromagnetic radiation, here in a range of radio frequencies (11000 MHz). To absorb a photon of electromagnetic radiation, the transition energy ΔEsample due to the interaction of a nuclear spin in the sample with a magnetic field mu...
