Equation ( ) also provides a good description of the effects of xdic on the changes in the other analyzed chemical shifts discussed above, namely, those of the CH3 group and 2 of the 3 hydrogen atoms in the aromatic ring (R 2 values ranging from 0.983 to 0.999; see Table .4, Supplementary Data). The values of the parameters in the equation presented above are provided in Table .4 (Supplementary Data). Therefore, with the known characteristics of this dependence, 1 H NMR analysis proves to be an excellent auxiliary tool for determining unknown molar fraction values of DSIL components on the basis of not only band integration but also chemical shifts of known signals in the spectrum.
