1H NMR Chemical Shift

The difference between the absorption position of a particular proton from the absorption position of a particular proton of a reference proton is called chemical shift. The chemical shift in Hertz is dependent on applied magnetic field while chemical shift in ppm is independent of applied magnetic field. Chemical shift gives an idea about the electronic environment. It depends on several factors. In this video, definition of chemical shift, different factors affecting chemical shift and scales of chemical shift have been discussion in detail.
