NMR- Solvents

Here you can find physical properties for some deuterated solvents:

 

Degree of Deuteration

Degree of deuteration [%] 99 99.5 99.8 99.95
Remaining concentration of protons [mol/l] 0.1 – 0.06 0.05 – 0.03 0.02 – 0.01 0.006 – 0.003
Advisable concentration of substance [mol/l] 0.1 0.05 0.02 0.005

    Is there any effect of changing solvents on the result?. I’m working on methanolic algal extract and I intend using chloroform as solvent for NMR due to the unavailability of methanol at the moment. Will there be any negative effect on my result?.

    In general, chemical shifts are solvent dependent. The sign and the value of the change in chemical shifts can are different. Dependent from solvent and substance.
