NMR signals of 133Cs have been measured in CsI, CsBr, CsCl, Cs2CO3, Cs2SO4, CsNO3 and Cs2CrO4 powders relative to a 0.5 molal aqueous solution of CsCl. Combining these results with the shielding constant of the solution, which has been determined in former measurements, the nuclear magnetic shielding of 133Cs in the crystalline powders can be given in an atomic reference scale. The theoretical values of the shielding constant of 133Cs in CsCl, CsBr and Csl agree only in the order of magnitude with the experimental ones. For 133Cs in Cs2SO4 a first-order quadrupole pattern has been observed.
