high‐resolution 1H NMRbrainIt is shown that high-resolution (1)H NMR spectra of intact excised tissues and organs can be obtained by rotating the sample slowly about an axis at the magic angle of 54 degrees 44' with the external magnetic field. In this way tissue and cellular damage ...
(1HNuclearMagneticResonanceSpectra,1HNMR)5.1概述 •核磁共振波谱，常用NMR表示，与红外光谱、紫外光谱一样，也是一种能谱。•测定这种能谱的依据，是一些原子核（如1H、13C、19F等）在墙磁场中会产生能量分裂，形成能级。当用一定频率的电磁波对样品进行照射时，特定结构环境中的原子核就会吸收相应频率的电磁波...
Chemical shifts (δ) in the 1H NMR spectra of free water and water adsorbed onto fumed silica, silicalite, and fumed silica/alumina were analyzed using ab initio calculations and experimental data. Nearly linear relationships between isotropic δH,iso values and the atomic charge of H (qH), th...
