## Abstract ^39^K NMR spectroscopy was used to study a blue potassium solution in tetraglyme containing 18βcrownβ6 and in a solution without the crown ether. Direct proof of the existence of potassium anions and complexed potassium cations in both solutions has been presented.
## Abstract Blue potassium solution in THF containing 18βcrownβ6 was investigated by means of ^39^K NMR spectroscopy. The presence of potassium anions and complexed potassium cations was demonstrated. Spinβlattice and spinβspin relaxation times were measured in the temperature range 176β295 K. An a
