Although various chemical theories have often been used to characterize hydrogen‐bonded systems with some success, they have been limited by the fact that the equilibrium constants were adjustable parameters. This paper reports a method to measure directly these constants by proton nuclear magnetic resonance spectroscopy. Results are reported for several systems and are used with a chemical‐physical theory to predict vapor‐liquid equilibria.
