Its importance for life and its unusual properties keep water within the focus of ongoing research; this focus especially applies to water in the liquid phase. Scientists agree that the hydrogen-bond network, which is formed by interactions between the water molecules, is key for understanding the anomalies of water. However, a better understanding of the structure of this network, as well as its dynamics, must yet be established. Soft X-ray spectroscopy allows the investigation of the local electronic structure of water by probing the occupied and unoccupied valence molecular orbitals. In this Focus Review, we present soft-X-ray-based techniques, their development in terms of liquid spectroscopy, and recent studies on the hydrogen-bond network of liquid water.
其对生命的重要性及其不寻常的性质使水成为持续研究的焦点；这一焦点尤其适用于液相中的水。科学家们一致认为，由水分子相互作用形成的氢键网络是理解水异常现象的关键。然而，人们必须进一步了解这个网络的结构及其动态。软 X 射线光谱学通过探测占据和未占据的价分子轨道，可用于研究水的局部电子结构。在本重点综述中，我们介绍了基于软 X 射线的技术、它们在液相光谱学方面的发展，以及最近关于液态水中氢键网络的研究。
