Abstract
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.
