Abstract

The differences in the resonance frequencies of protons in water and hydrogen are determined for cylindrical samples using an electromagnet (B = 2.142 T) and a superconducting magnet (B = 11.747 T). The difference in the chemical shift for protons in water and hydrogen is found to be σ(H2) – σ(H2O) = 596(2)·10–9 at 25°C. The published value of the absolute shielding by protons in hydrogen, σ(H2) = 26288(2)·10–9 at this temperature, implies σ(H2O) = 25692(3)·10–9, which differs from the shielding by protons in water σ(H2O) = 25694(14)·10–9 given in lists of the fundamental physical constants.
