Isotope effects on gas phase reaction processes. I. The determination of equilibrium isotope effects by ion cyclotron resonance spectroscopy

Measurement of hydrogen/deuterium ratios in ethanol/ethanol-O-d mixtures by chemical ionization mass spectrometry with tetramethylsilane as reagent gas

“…Another possibility is the presence of a secondary isotope effect operating on the simple silyl transfers between water and ethanol. Since the whole trimethylsilyl group is transferred, the isotope effect is unlikely to have a large enough magnitude to account for the observed results (19)(20)(21)(22). Competition for exchange and reversion to reactants could occur; however, as discussed below, reversion to reactants is unlikely.…”
