Application of nuclear magnetic resonance/magnetic resonance imaging techniques to estimate proton relaxation parameters in various solvent at Earth field

Abstract

The nuclear magnetic resonance (NMR) field of earth may be utilized to estimate proton relaxation parameters in different liquids. In liquid samples, it can quantified proton relaxation durations T 1 and T 2 , along with the self-diffusion coefficient D, thanks to the magnetic field of the Earth. It was proved that it is feasible to distinguish between liquids based only on these characteristics by analyzing a wide range of liquid samples. In this paper, it was investigated whether it is possible to utilize Earth’s magnetic field Nuclear Magnetic Resonance (EFNMR) so as to correctly and practically quantify T 1 and T 2 along with the self-diffusion coefficient D. These findings pave the way for additional research into the use of EFNMR for the determination of relaxation parameters. It was acquired two-dimensional 1H NMR images of 50 ml of toluene solvent at low frequencies using the magnetic field of the Earth.
