Nuclear magnetic resonance studies of 14N and 1H in metal-ammonia solutions


, : Nuclear magnetic resonance studies of 14N and 1H in metal-ammonia solutions. Journal of Physical Chemistry 88(23): 5608-5614

The Knight shifts and spin-lattice relaxation times of 14N and 1H in sodium- and potassium-ammonia solutions have been measured as a function of temperature and composition up to the saturation region. The hyperfine interaction between these nuclei and paramagnetic unpaired electrons from the dissolved metals is responsible for the shifts which increase with increasing metal concentration.
