2,2,6,6-Tetramethylmorpholine

2,2,6,6-Tetramethylmorpholine (TEM) is a chemical compound that is used in the synthesis of other chemicals. It is an electrolyte with a high dielectric constant and has been used as a solvent. The TEM molecule has two hydrogen isotopes: deuterium and protium. Deuterium has higher mass than protium, so it has different kinetic properties. In voltammetry experiments on TEM, the voltammogram obtained from deuterium-substituted TEM is shifted to a more positive potential than for protium-substituted TEM. This can be seen by examining the difference in the kinetic curves for each of the isotopes.
