1H NMR chemical shiftStacking interactionAssociationPurine6‐MethylpurineMutually induced proton chemical shift changes were measured for purine-6-methylpurine solutions in deuterium oxide at 35° C. The chemical shift vs. concentration profiles were analysed using a three-state decomposition model based ...
Chemical shift, also known as the nuclear magnetic resonance (NMR) proton spectrum, is a fundamental technique used in chemistry to determine the chemical environment of hydrogen atoms in a molecule. In this article, we willexplore the concept of chemical shift in detail and discuss how it is ...

Chemical shift imaging combines the spatial information provided by a conventional nuclear magnetic resonance (NMR) image with the chemical shift spectral information provided by NMR spectroscopy. In order to preserve the chemical shift information and provide a spatial map simultaneously, new NMR imaging...
