A liquid microjet was used to obtain oxygen K‐edge X‐ray absorption and emission spectra of water–acetonitrile mixtures of various compositions. The observed spectral changes are unambiguously related to the increasing number of broken hydrogen bonds with decreasing water concentration, and the hydrogen‐bond network of liquid water can thus be addressed on purely experimental grounds without the need for theoretical modeling.
