Abstract: 1H, 17O and 35Cl NMR chemical shifts of rare earth aqueous solutions were studied.The hydration number and hydrate configuration determined were as follows:The hydra-tion number of Pr, Nd ions is 9 and their hydrate configurations are tricapped trigonal prismatic. The hydration number of Tb, Dy, Ho, Er, Tm, Yb ions is 8 and their hydrate configurations are square antiprismatic. The hyperfine coupling constant between 17O and 4f electrons of rare earth ions was also calculated.
