The result is the water hardness expressed in grains per gallon. For example, say you have a water hardness value of 180 ppm. The same solvents are used for 13 C NMR spectra, so the same rules about splitting patterns apply here also. It used to be common practice to add Me 4 Si, or related compounds, as an internal reference standard for 1 H and 13 C NMR spectra with the proton signal occurring at 0.0 ppm and the carbon signal occurring at 0.0 ppm in the 13 C NMR spectrum.

6 containing 100 ppm D 2O. The problem becomes worse as the molecular weight of the analyte increases. Solution: Water (as H 2O, HDO or D 2O) can be minimized by adding molecular sieves to the solvent, agitating the mixture and allowing it to stand for a few hours. The water content may be reduced to about 10-20 ppm in this manner.
