Magnetic shielding studies on the alkali molecules Na2 and Cs2 by NMR

  • Published:
Zeitschrift für Physik A Atoms and Nuclei

Abstract

NMR in the alkali molecules Na2 and Cs2 is performed by the atom-molecule exchange optical pumping method. The shielding differences σ(Na)−σ(Na2)=(29±16)·10−6 and σ(Cs)−σ(Cs2)=(221±12)·10−6 are obtained. The investigation of the contribution of the valence electron to the magnetic shielding is supported by a NMR experiment in free Cs+ ions, which yields the shielding difference σ(Cs)−σ(Cs+)=(14±12)·10−6. These measurements allow an estimation of the spin rotation interaction constant in these molecules.
