Caesium hydride (CsH) is a compound of caesium and hydrogen. It was the first substance to be create by light-induced particle formation in a metal vapor.[1] It also showed promise in early studies of an ion propulsion system using caesium.[2]
The caesium nuclei in CsH can be hyperpolarized through interactions with an optically pumped caesium vapor in a process known as spin-exhcange optical pumping (SEOP). SEOP can increase the Nuclear Magnetic Resonance (NMR) signal of caesium nuclei by an order of magnitude.[3]
Crystal Structure
At room temperature and atmospheric pressure, CsH has NaCl structure
