Table 1.

Differences between the FSTO and SNTO frequencies and corresponding mistuning parameters Ξ [Eq. (14)] as a function of the salt concentration cNaCl in a H2O : D2O=1:1 sample on a 700 MHz TCI cryo-probe (see Supporting Information)

cNaCl [mmol L−1] (ωSNTO−ωFSTO)/2 π [kHz][a] Ξ[a]
0 −236±19 −0.42±0.05
100 −235±29 −0.20±0.03
200 −318±38 −0.20±0.03
300 −335±28 −0.15±0.02
500 −433±81 −0.15±0.04

[a] The reported uncertainties correspond to fitting errors. Since FSTO and SNTO frequency values do not conform to the theoretical model predictions, some systematic errors are present.
