solid-state nuclear magnetic resonance spectroscopy 23Na nuclear magnetic resonance spectroscopy 23Na solid-state nuclear magnetic resonance spectroscopy https://orcid.org/0000-0001-5985-7429 Spectroscopy where the energy states 23Na nuclei in a solid sample placed in a static magnetic field are interrogated by inducing transitions between the states via radio frequency irradiation. Each experiment consists of a sequence of radio frequency pulses with delay periods in between them. 2009-05-14T12:35:58Z 23Na solid-state NMR CHMO:0001296
