Technologies including NMR relaxation time estimation methods and corresponding apparatus are disclosed. Example techniques may generate two or more alternating current transmit pulses with arbitrary amplitudes, time delays, and relative phases; apply a surface NMR acquisition scheme in which initial ...

This model in (8.1.3) is commonly used in the place of Fourier's law if finite speed of heat propagation is considered. In the relaxation model (8.1.3) a delay of time τ in the heat flow is there but the heat release is not instantaneous at timet+ τ and is distributed over a ...

We study the role played by the magnetic frustration in the antiferromagnetic phase of the organic salt κ-(BEDT-TTF)Cu[N(CN)]Cl. Using the spatially anisotropic triangular Heisenberg model we analyse previous and newly performed NMR experiments. We compute the 1/Trelaxation time by means of ...
1) NMR relaxation time NMR弛豫时间1. NMR relaxation times of four protons at different positions versus steric effect and mixing proportion in ligand mixtures were monitored. 实验监测了配体中不同位置的质子的NMR弛豫时间随空间距离及配体比例改变的变化情况 。
