Paramagnetic nuclear magnetic resonance spectroscopy refers to nuclear magnetic resonance (NMR) spectroscopy of paramagnetic compounds. Although most NMR measurements are conducted on diamagnetic compounds, paramagnetic samples are also amenable to analysis and give rise to special effects indicated by a wide chemical shift range and broadened signals.

Technically, they are repelled by the poles of a magnet, but this repulsion is usually too small to notice. Paramagnetic compounds contain one or more unpaired electrons and are attracted to the poles of a magnet. powerapps format datetime as date
