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 hydration 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.
