Caesium hydride (CsH) is a compound of caesium and hydrogen. It was the first substance to be created by light-induced particle formation in metal vapor,[2] and showed promise in early studies of an ion propulsion system using caesium.[3]
The caesium nuclei in CsH can be hyperpolarized through interactions with an optically pumped caesium vapor in a process known as spin-exchange optical pumping (SEOP). SEOP can increase the nuclear magnetic resonance (NMR) signal of caesium nuclei by an order of magnitude.[4]
Crystal structure
At room temperature and atmospheric pressure, CsH has the same structure as NaCl.
